DS has just moved to Secondary School. He had had a friend at Primary School that he'd fallen out with, although he hadn't made a big deal of it so the friend hadn't realised. DS had hoped that things would just fizzle out naturally as they went to different secondary schools. However, this other boy's parents have been contacting me as they are keen for the boys to stay in touch. DS is adamant that he doesn't want to see the boy ever again. His reasons are valid, in my view. In Year 6, a new boy joined the school and DS and he became close friends. The other boy was (I imagine) v. jealous, although DS liked them both equally and wanted them all to hang out together. DS kept trying to make them all get on, but to no avail. The other boy became extremely unpleasant to the new boy - and said some vicious, cruel things to him regarding a very serious medical condition he has which DS thinks was unforgivable. After that, DS's feelings towards the other boy changed irrevocably, but he didn't make a big scene about it. This other boy has definite behavioural issues (think was thrown out of a previous school), but they used to get on well and his parents are delightful people. His parents are pressing me to arrange a get together.What do I do? DS refuses to contact this boy directly to explain (via email) and wants me to handle it - which I understand. I suppose I have to speak to the mother (in person?) and just be truthful??? Very awkward.I know the parents are v. worried about their son's social problems as it is and were relieved he finally had a proper friend. Would love to hear how people think I can best handle it???? TIA.
