Mum at school with DD in same class as my DD. Notorious for never replying to party invites, having to be chased, never knows what she is doing on the day 'Can I let you know later' etc etc.
Just handed out invites for her DD's party 6 weeks in advance, so 'she can be organised'.
The bloody cheek of some people. Makes my blood boil.
AIBU to let her bloody sweat and not respond
