people now-a-days

poeple like to play with people emotions and HIT THEM like they are just a zoo animal and dont have feelings,  truth is ANIMALS HAVE FEELINGS TOO. people isn't considerate now-a-days and i dislike that and one day when i be mean to them they not going to like that and im going to act like i dont care. than im going to be looked at like im the bad person when im not, so should i keep being there friend or give them what they want?
