difficult child had a friend over yesterday playing tether ball outside. Apparently difficult child won, and friend started swearing at difficult child, so difficult child swore back and friend left. That was late morning. Then in the afternoon difficult child called friends house, and no one answered, so he left a message. Calling friend a m***** f***** and demanding he answer phone. Friends mom called worried because whenever difficult child is over there apparently he is always "respectful" and a good kid (aliens steal him once in a while). husband spoke with parent (I was at work) and difficult child is grounded. I don't know what to do about this friendship. This type of thing, the arguing and fighting, happen often. Is this normal? It just seems wrong to me, but what do I know. I hate to tell difficult child that he can't be friends with the boy as this is the only kid in the neighbor hoood who plays with difficult child. At the same time, I do not think this boy has a good home life, and I do not know what goes on there. They play over here, and difficult child only rarely plays over there. I am at a loss. I do not know what to do about this friendship. Do all kids argue with their friends this way? Is it a boy thing, cuz I do not remember doing this.
