I opened the door at Halloween to most of my DD’s Y2 class (and parents). Someone had organised a party followed by trick or treating and not invited my DD. Then they had the gall to knock on my door and ask for treats en masse. My DD was upset and confused about why she hadn’t been invited and I was livid. While she hadn’t been invited to the house party (presumably as the Mum doesn’t like me), I really think one of the parents could have asked us to join them all. When I told other friends about this I was told I was being unreasonable. I don’t think I am. Thoughts?
