A friend of mine has a teenage son who is quite difficult and has a bit of a "bad reputation". She also has a perfectly lovely 8 year old. She is very upset, as some parents have apparently said that their children can't play with her younger son because of his big brother, and he's naturally very upset.
Why would an adult behave like this? Fwiw, the parents are lovely, and younger son is no trouble at all, well behaved and sweet. Aibu to think my friend is right to feel upset and angry on her ds2's behalf?
