Summarize the following:
The most common method of smoking indoors is by finding a window and aiming your smoke outside. Not only will the smoke now have somewhere to go, you'll also have fewer issues with a lingering smell. The most common method of smoking indoors is to stand next to a window, leaning into it, and exhaling the smoke outdoors. The way you go about it will depend on the shape, position, and size of the window; anything is fine so long as the smoke is getting outside as fast as possible.  If you have a portable fan, try putting the fan next to the window, aiming outwards. When it comes time to exhale, exhale into the fan from behind it. The fan's blades will subsequently hurl the smoke outside. If you're by a window and are looking to not get caught, you should keep an eye on your surroundings outside. If someone's outside, it might look suspicious that you're leaning out your window. Exercise alertness and caution. Keep your hair out of the way. If your hair is long, it's a good idea to tie it back; that way, your hair won't pick up as much of the odor. While you're at it, you might want to take off any extra layers of clothing you might have. Anything you're wearing is going to pick up some of the smell, so it's a good idea to minimize what you're wearing before you smoke. At last, you can enjoy your smoke! Beware, however, for anyone that might come in or see you while you're smoking. Any amount of time you have the smoke in your hands increases the risk of being caught, so try to keep the experience short and sweet. Make sure to have somewhere you can quickly discard your cigarette in case someone enters the room. If you're fast and fluid enough, you might be able to get rid of it without them knowing you were smoking to begin with. This includes keeping both ears alert for sounds in other rooms, or footsteps that sound like they're heading to your room. If it's really important you're not caught, staying alert and on-edge may give you a few seconds extra notice, and those seconds could mean the difference between getting caught and getting away with it. Even if you sprayed some air freshener before diving into your smoke, it doesn't hurt to give your room another round with it. That way, the freshener will be the most recent smell in the room, and others will have a harder time picking up the unwanted scent.
Aim out a window. Minimize the risk of picking up the smoke's smell. Smoke. Be wary of others while you're smoking. Spray an air freshener once you're done.
