everyone has a past and a story be it interesting or boring it's still a story and a past.
the past changes people.
just think next time you see someone before judging them think what they are going through and if you don't know then you have no right to judge.
someone may have trouble at home and be a jerk to others so that he/she won't get hurt.
someone may be going through a death so she/he cries at the mention of it. that doesn't make them a wimp or a cry baby.
someone might drink a lot to drive away stress. doesn't mean they are just an irresponsible kid.
someone might fight just to get through it all. it doesn't make them a terrible person.
everyone has a story. just make sure you know what you are saying.
