8. Stinking farts
Everyone has to pass gas at some point, but that does not mean that other people want to smell the contents of your colon. No one likes to smell a fart. This is particularly true of a fart that is smelled in the public domain.
Nothing is worse than walking down the aisle in a department store and finding yourself immersed in a cloud of someone else’s ghastly rectal gas, or standing in an elevator that smells like a recently-used toilet. If you have to break the wind and you know you are probably going to stink, go to the bathroom or at least do it in an empty space.
