It usually feels pretty good to know someone's crushing on you, whether or not you return the favor. But crushes can disappear as quickly as they appear. So consider this a friendly reminder to behave yourself. You never know when someone who's crushing on you could be watching.
1.) From ApostropheJ:
My brother had a friend just after high school that was super hot. He was also really nice to me and had manners when he came over.
Flash forward a few years, he's helping my brother and I with a tree removal job. He starts chewing tobacco and spitting it EVERYWHERE on this person's property, pees in their bushes, brags about having 5 kids by different women and that he doesn't pay child support, that he was a "fifth year senior, dude, haha!"
