I moved into a new house we bought earlier this year with my husband and 3 small children. All the neighbours around us are similar ages to my husband and I with children similar ages to our kids. They are all quite good friends as they’ve known each other a few years now. We are friendly with them and they are quite chatty out the front. Today they had “neighbourly” Christmas drinks at one of their houses and they were all invited except for us. If it was just the “old” crowd it wouldn’t be so upsetting, but they invited 2 families that have moved into the street after we did. They also had ample opportunity to say something about it as we spend a lot of time today out the front putting up xmas lights. I am quite upset about being left out and don’t know how to approach it. I can’t think of anything we may have done to upset them and my children are well behaved. Do I say something? Thank you.
