In one sentence, describe what the following article is about: If you want to kiss your partner in public, you can. That doesn't mean you can let that kiss progress into a make out session. When going in for a public kiss, use some discretion. Kissing in public is fine as long as you don't overdo it. Don't use any tongue, and don't put your hands under your partner's clothes. Anything more than a closed mouth kiss may start to make people uncomfortable. Kissing in public isn't always acceptable. Even if you think no one is paying attention to you, it may not be a good time to start kissing.  For example, just because you're in a dark movie theater, doesn't mean it's okay to start making out. You may be able to get away with a quick kiss on the cheek, but don't push it because you think no one can see you.  Avoid kissing in places with large crowds, such as restaurants or grocery stores. An exception to this rule is nightclubs. It's common to see people kissing and dancing at nightclubs. If you're out and you feel like kissing, you're probably in the clear. In some countries, kissing in public is a serious offense. In most Western countries if someone disapproves of your kiss, you should only have to worry about a dirty look or two. But, in places such as India, kissing in public could land you in a lot of trouble. If you plan on traveling with your partner, research some of the customs before you leave. Look for laws regarding all types of public affection. Don't limit your research to just kissing. For example, in China, holding hands is also prohibited between couples. No matter where you are, respect other people's boundaries. Don't force a kiss on someone who does not want to kiss you. Nobody appreciates unwelcome physical advances. Don't use public affection as an ego boost. Kissing in public should be about sharing a kiss with someone you enjoy spending time with. Don't use it as a way to communicate to the rest of the world that your partner is "taken."
Summary: Keep it clean. Be aware of your surroundings. Be aware of social customs. Make sure it's consensual.

In one sentence, describe what the following article is about: Threaded headsets have one continuous metal piece (stem) that comes up out of the frame, bends forward, and then attaches to the handlebars. There is a nut where the stem leaves the frame that holds it in place and one bolt at the top of the stem. These stems are easy to adjust and are common on single-speed, fixed gear, and older bikes. Some bikes do not have a hex nut by the frame, and just have the bolt on the top of the stem. This bolt, pointing straight down, creates the pressure that holds the stem in place. Use an Allen key to loosen in, though your don't need to remove it entirely. Disengage the hex nut, which is the "ring" where the stem meets the bike frame, by loosening it with a wrench. You may need to wiggle, twist, and pull to get them out. If this is a new bike, mark the location where the handlebars used to rest with a marker or measurement so that you can return to this location if you need. Clean off any gunk on the stem with soapy water and then dry it with an old rag. To prevent the stem from getting stuck in the frame later on, apply a little anti-seize grease around the bottom 2-3 inches of the stem. Proper handlebar positioning largely depends on the type of bicycle you're using. That said, the number one concern when picking a height is rider comfort. You should put the handlebars where you can comfortably ride every time.  Road bike: Handlebars on racing bikes should be slightly lower than the seat to provide optimum aerodynamics and control at high speeds. Mountain bike: Mountain bike handlebars should be lower than the seat. This gives you a lower center of gravity and better balance when negotiating rugged terrain. Cruiser: Handlebars on standard bikes should be slightly higher than the seat to limit strain and provide maximum comfort. Hand tightness should be fine, especially with the top bolt. You don't want to crank on the bolt, making it so tight that you can't remove it later.
Summary:
Know if you have a threaded headset. Loosen the bolt on the top of the stem. Loosen the locknut with a wrench. Pull the handlebars out of the frame. Wipe down and grease the stem lightly. Consider the kind of riding you'll be doing when deciding a new handlebar type. Place the stem back at your desired height and tighten the hex nut and top bolt.
