I invited a few friends over for dinner on Saturday evening. These days we really only get together as a group about once a year so I was really looking forward to a good catch up. One of my friends (who has two children aged 7 and 9) rang me yesterday to say that her babysitter has had to cancel. I was about to say 'oh dear. We'll really miss you' or somesuch when she just continued with 'but they won't be any trouble and I'll make sure they bring things to play with'. 
AIBU to be really pissed off now? They're both a bit spoilt and attention seeking to be honest, but even if they weren't I really don't want two young kids sitting in our midst.
