Long story but, I was poping to my sister's on Saturday to pick up a xmas present for another relative, we were running late. We managed to catch her up as she was walking into town with her daughter. Having spoken to her briefly, DH pulled off in a rather abrupt way and frighten my niece. This was then followed with text messages to me (not DH which IMO she should have directed them too) calling him an ignorant sod. I apologised for the abrupt exit, but she followed up with another text later to ask if my ignorant sod had calmed down. Now we have no secrets in our house and unfortunatley DH was nearest my phone when it went off. So he was not at all pleased and followed it up with a text to say that paths were for pedestrians and roads were for cars and that she perhaps ought to teach that to her children (he does not agree with the way she bringing them up - too soft etc etc etc. Not my opinion..his) This then started a text row to which both parties have gone way over the top and I am stuck in the middle. I have decided to not take sides and let them sort this out on their own. But we are due to have my neice and nephew for a sleep over on Sat (sisters xmas do. 3rd time out in as many weeks!) Also due to go for xmas day. Can't believe this is happening... wish that they would both grow up! Any suggestions as to what I should do next?
