My 12 year old son had an argument with one of his best friends at the beginning of the summer.  I thought time would heal things but he is still troubled with the situation. He also talks to some of their common friends about it. Apparently (and rightly so), the other friends want to stay out of it and don't want to hear about it. I adviced him not to talk to others about this friend (more generally stay out of negative discussions). He is extremely sensitive and I could see his eyes were became red and wet. In general, whenever when we advice him to change his behavior, this is how he responds. I would like to hear your opinions on how to give advice in general and also on how to deal with the problem with the friend. Thanks so much.
