Back on track

My brother's name is John, and he is sexteen years old. He has a bad habit that he is taking coke, almost every day. I have told him that he should stop take so much, but he will not listen to me. I tried to help him by asking him if he wanted me to call to a rehab. He always says no. One week he didn't take coke. and I was very happy for him. I saw him in the garden, so i walked slowly down to him and asked him if he was okay. he said to me, that he was okay, so I went back up to my room. after abit, I went in to john's room and there I took his bag and looked in it, I saw alot of coke. I was about to take it when he came back up on his room. He asked me first what I was doing, I told him that I was cleaning his room. but he didn't trust me, and kicked me out of his room. I went outside to Talk to my friend jack . I asked him if he wanted to help me to get my brother stop taking coke. He said yes and asked me what the plan was. I told him that i want him to play a "coke dealer" and he said yes. Next day when my brother was in school I went up to his room and took the most of his coke. I went out to my friend and gave him the coke and a fake gun. The clock was almost seven when my brother was on the way home. When he was on the street we lived in jack came out and asked him if he wanted to buy some coke, he said it was very cheep and it was good coke. my borther said yes and gave him all his money and went home. Next day my friend jack was knocking on the door and I went down to open. when i opened he said hey and asked after John. I called after john and he came down. John asked jack what he wanted, and jack said he had cheatet him and he wanted his money back. But there was one little problem, john had used them all. But when john didn't pay, jack pulled his fake gun and point it at john's head. John was in chock and was crying. I pushed jack and closed the doore, and said I would call the police if he didn't go. jack run away so he didn't ruined it the "show". I told john that I would protect and never let him down, there was a little brake and I asked him if he wanted go on rehab so he didn't get in to all this problem's. He said yes and he thanked me many times. After a month he came home from rehab. I was almost sleeping when he came in to my room and said to me "brother I wanna start a new life and you shall help me if I get in to problems will you promis that?", I said "yes borther i will promis that, but lets now go to bet and start your new life to morrow, goodnight borther.....
