Think I'll do nothing about this, but need to rant..
We've recently moved abroad and live on an ex-pat compound with loads of other familes. Now, there are kids parties here once every couple of weeks, in fact, we had one for DS2 in April, to which everyone is usually invited. Just found out there was a party for one of the kids yesterday and my boys were the only ones not invited.
Am I being unreasonable to think this is really mean? I didn't even think the mother had an issue with me. We don't even speak that much and when we do it's friendly enough. Am puzzled! By the way, she's not the type to forget to invite people so it was deliberate. The kids are only 4 and 3 years old.
