My MIL is normally quite lovely. She is something of a character and can be a bit odd but her heart is in the right place and DS loves her. DS stayed at her house on Friday night and came back to us on Saturday. WHen he got back it was obvious that he had had his hair cut - badly. It look chewed rather than trimmed. MIL has done this before TWICE and we have asked her TWICE not to do it. DH called her at home to tell her again that ideally we would like to make the decision as to when and how DS has a haircut OR failing that could she please call us and ask us before she goes ahead and gets it cut. DH had only managed to say "Mum, has DS had a hair cut? When she started screaming at him that she hadn't done anything and then she hung up on him (!) DH was taken aback and called back to say hang on, let's not go crazy but his Dad answered the phone and started shouting that DS hadn't had a haircut at their house and that we were calling them liars. Then he hung up as well. DH called back again because he was so shocked by their angry response that he wanted to diffuse the situation. MIL answered and she was sobbing telling us that we had ruined their afternoon that we had made FIL ill, that he was having a hypo (he has diabetes). Then DS pipes up that he had his hair cut at DH's aunty's house. MIL denied this, said she wanted nothing more to do with us and hung up again. We decided not to call back again but to leave it overnight and try to reason with them in the morning. However, the phone rang and it was DH's Aunty. She said that MIL had called her, that we were breaking MILs heart and that neither of them had cut DSs hair. She then said that he must be confused because whilst he was there she had been having her hair cut by the local mobile hairdresser! As soon as she said this I knew that all three of them were spinning us a line. I knew DSs hair was shorter, I'm his mum FGS and yet three people were telling me categorically that I was imagining it.
We need to resolve this today but as long as the PIL are denying that they cut DSs hair there is nowhere for this to go other than DH and I apologise to them which seems so unfair and would stick in my craw. Anybody got any ideas on how to handle this?
