A 15 year old girl holds hands with her 1 year old son. People call her a slut, no one knows she was raped at 14. People call another guy fat. No one knows he has a serious disease causing him to be over weight. People
call an old man ugly. No one knew he had a serious injury to his face while fighting for our country in the war.
We are not complete enough to judge about their physical appereance or their surrounding...just be quiet and you will fine :)
