My DS is 10.7. My friend's DS is 9.7. My son is outgoing and friendly, engages in physical play, but knows when to stop, and he is rarely aggressive. He mixes well with children of all ages and of both sexes, generally. My son's DS is very tall and strong for his age. He's a real man's man, and is very rough at times. He often rugby tackles my DS to the floor, and has caused injury on more than one occasion, despite being asked numerous times not to do this, both by my son and by myself. He bear hugs him, which sometimes leaves my son winded. He shouts my DS down in a conversation if he doesn't agree with him. His Mum finds her DS a handful, and constantly criticises him to me in front of the child, which I have asked her not to do. She complains that he does not do as she says, and that he completely disrespects his father. She does not, however, ask her son to stop being so overpowering to my son, and defends him if I step in (which I feel I have to do eventually - considering my son is lying flattened on the floor, near to tears!). I have been very careful to be calm when dealing with the situation, explaining to both boys that if one of them decides to deal with a situation by being aggressive, they will lose friends, and that it is not acceptable to continually do something to someone (ie: rugby tackle, bear hug) once someone has asked you not to. My friend's DS is also quite rude and tactless, telling mine that his interests are boring, that "only braindead people play Yu-Gi-Oh!", that I feed him a bad diet, (this comment would seem to originate from his mother, don't you think?). My son says he is tempted to be rude back, but that he doesn't like having his feelings hurt, so wouldn't want to do it to someone else. My problem is that I really like his mother as a person, and we get on well. She infuriates me as a mother though, and is not consistent in how she deals with her children. She doesn't seem to pick up on my subtle attempts to address these issues, but I know she would be devastated if I were really blunt - and I'm useless at confrontation! Advice please on how to address these issues and support my son, yet remain mature and objective, and hopefully still have a friendship! Thanks.
