understanding

sometimes, i find myself trying to understand people or certain situations that perhaps, i will NEVER understand. and i have to admit this is extremely trying. i dont understand why certain people behave in such a manner that causes pain or hurt to someone else. i mean, knowingly do it. it's one thing if you hurt someone and you dont intend to. i mean, people do that everyday. but it boggles my mind how people can do something to another person that they KNOW hurts that individual without any regard for that person. ugh!!!
