It's probably always been this way, but doesn't it seem like there are a lot of a**holes just everywhere nowadays? We are social animals, we have to deal with each other every day. Why make things so awful? Just... simple stuff. Be polite, pay attention, toss out a kindness every now and then. And if those things are too tough, then, please, at least just stop being such a jerk. Vote for the ones you wish more people would obey, and add whatever you think is missing.
