Summarize the following:
Always call your local utility companies to make sure there aren't any underground utilities beneath the concrete. Hire a professional if there are. Digging above a utility line like gas or electric can be very dangerous. Concrete removal creates hazardous dust and sharp fragments, so protect yourself and your coworkers with safety goggles, dust masks or respirators, steel toe or other heavy boots, thick gloves, and thick clothing that covers your arms and legs. If you're going to be using power tools, especially a jackhammer, use ear protection. Be careful when using plastic sheets, as they can sometimes create a slipping or tripping hazard. However, sheeting can be worthwhile if you're breaking up concrete near fragile items or structures.  If you're breaking up concrete in a wide open area away from structures and other breakables, it's unlikely you'll need sheeting. Fragments of concrete can be launched great distances by the force of your hammer and tools. When in doubt, use a cover to protect the surrounding area. If you don't use plastic sheeting, protect any nearby windows and breakable objects with plywood sheets to protect the glass from concrete fragments. Whether you're using a sledgehammer or jackhammer, you'll likely need to pry apart the pieces of concrete as you break them apart. Concrete removal generally goes quickest if you have one person breaking apart the concrete and another following along and prying the pieces apart. If your concrete is 4 in (10 cm) thick or less, try using a sledgehammer. Start at any existing cracks or at a corner or edge, and keep in mind that thick concrete will be easiest to break closer to its outer edges.  Don’t try to swing the sledgehammer or lift it above your head; hold it at shoulder-height and let it fall onto the concrete, instead. Use the pry bar to pull apart the chunks of concrete after you break them apart. Then, move them out of the way to eliminate trip hazards. If after 10 minutes you've failed to make significant cracks or you are exhausted, you may want to try a  demolition hammer. "Undermining," or removing soil beneath the slab, will make the cement break more easily. Use a shovel to clear out the soil beneath the lip of the concrete, then strike it with your hammer.  The more you undermine a slab, the easier it'll be to break. However, even undermining a little can significantly decrease the difficulty of breaking concrete. After you’ve begun to undermine, use a garden hose to loosen the dirt and wash it out from underneath the slab. A 60-pound (27.2-kg) breaker should be sufficient for most home jobs. Only rent a heavy duty pneumatic jackhammer for extremely thick or difficult to break concrete.  Only use a chisel point bit to break up concrete. This concentrates force, allowing the tool to break up the concrete more efficiently. Let the weight of the machine do the job; it's not necessary to add force by pushing down. Forcing the bit may damage the tool or possibly wedge the bit. If the concrete doesn't crack immediately, stop hammering and move over a few inches. More hammering could get the drill bit stuck. Break pieces 2-3 inches (5-8 cm) away from each other to minimize chances of a stuck drill bit. Use the pry bar to pull apart chunks of concrete after you crack them apart. You may encounter supports inside the concrete after you start cutting. Deal with them as you separate the chunks of concrete:  If the concrete is held together by wire mesh or heavy, welded wire fabric, you'll need bolt cutters to snip it apart. Number 10 wire can be cut with side cutting pliers. Metal reinforcing bars will take much longer to cut apart. Use a reciprocating saw or an angle grinder with a cutoff blade. If chunks of concrete remain locked together, making it hard to break the surrounding area, clear the surrounding rubble. After that, you're ready to use a heavy mattock to pry locked chunks apart:  Swing the pointed end into the crack between the two chunks and pry. Once the crack is wide enough, switch to the larger flat end and pry it fully apart. Pry up the opposite side of each chunk if they still won't budge.

summary: Call your utility companies. Use safety equipment. Cover the slab with plastic sheets to protect fragile items. Obtain a large pry bar. Use a sledgehammer for thin slabs. Dig underneath slabs that are difficult to break. Use an electric demolition tool. Deal with any mesh or reinforcing bars you encounter. Pull apart jammed together chunks with a mattock.


Summarize the following:
If you’re not sure what to bring, ask your host. They may tell you not to bring anything out of politeness. In this case, respect their request; although, you could still give them a card or a thoughtful note. If you can’t bring a gift, a bottle of wine or vase of flowers are good options.  Potluck: a dish to share. Birthday party or baby shower: a gift suitable for the recipient. Dinner party: a bottle of wine or a hostess gift. Casual high school or college parties: no gift, unless specified. Try to get plenty of rest the night before the party. That way, you’ll be able to stay up late if it’s a late night party. Even if it’s a daytime party, you still want to have the energy to be sociable and feel your best.  Some people will drink coffee or another caffeinated beverage before going out for a late night party. Eat a protein-packed meal before going out. Even if there will be food at the party, you don’t want to arrive starving. Listening to some of your favorite music is the perfect way to get excited about a party. It can get you energized and ready to dance, or just put you in a good mood.  You can listen to music while you’re getting dressed, or while you’re driving to the party! Sing along. You’ll feel confident and expressive, which is a great way to feel when you arrive at a party. Think about who will be at the party and how you want to interact with them. This can be especially useful if you’re shy or don’t go out very much. You can make small goals, such as, “I will talk to two new people,” or “I will introduce myself to my new coworker that I have a crush on.”  You can even practice in the mirror if you’re really shy. Practice introducing yourself to someone by saying, “Hi, I’m ___. How do you know the host?” Think of topics you can talk about with other guests. Do you follow current events? Have you been working on an interesting project? Can you share a humorous story about the host? Usually, it’s assumed that people will arrive at a party a little bit after it’s supposed to start. This is called being “fashionably late.” If you’re shy, you may want to arrive well after the party has started so that you can avoid having to make conversation if there are only a couple of people there early on. Don't be late to dinner parties, children’s parties, or parties where a space has been rented for the occasion. Doing so is considered to be rude. Aim to arrive on time.
summary: Prepare anything you need to bring. Get energized. Listen to music. Plan for socializing. Decide when you’ll arrive.
