Yeah so I am 16 and my brother is 18. We have become considerably closer as brothers the past year or so. He has recently been starting to smoke cigarettes regularly and I worry for him. Should I tell him to stop or tell him how I am feeling or what? On one hand I really don't want to smoke because it kills and I want the best for him but at the same time I don't want to be his mom and I realize he has the right to do whatever.
