Will try to keep this concise! Neighbours (and friends) are a family of 5 coming to our house tomorrow for NYE, it has been arranged for a couple of months informally but we confirmed plans before Xmas.
We have similar aged children and hoped for a nice relaxed evening - few drinks, nibbles etc. whilst kids watch a film/telly and play with Xmas toys.
My DH is fairly shy antisocial but is happy to host and over the years we have got to know this family. It's taken a good couple of years to build up to this. I received a text a few hours ago asking if we could also entertain their friends who have decided to visit them tomorrow evening. They are a couple with no kids (not really relevant, just emphasising it's not a family of 6!) and we have never met them before. The wording of the text made it clear that their friends knew they would be asking us.
AIBU to not want to change the plans we already have? I sent a text back saying they are welcome to come round for a drink, but I'm really not that happy..... Am I a horrible old cow for being annoyed?
