Friends!!!!

Friends!!Wat is a friend?Who is a friend?In my views a friend is a person or animal who helps out his friend in gud ways,help to get on the right track if he or she goes in the wrong way.Now adays school students pick their friend from their attitude,looks & actions.When i say action i mean things tht seems fun for them but things tht can hurt someone.I actually picked one friend who cud do better in his studies and attitude.I thought i cud help him.At tht time he was with some uncivilized group of children.If one word can describe them it wud be ''rowdy''.I feel guilty now.Hes out of reach now.He calls me his friend.But I dont think tht hes my friend now.....I wud like to ask u a question........Wud ever consider a person who critisize u evry chance he gets,a friend?Wud u ever consider a person ur friend who says upseting things to u and doesnt think before he speaks wat the others might feel?Some one who wud be ready to in every bad action?....I dont think i wud!But still im not able to cut my friendship with him.Can anyone giv me some advice?!?!?
