Just wrapped up on my DC's party.
If you've RSVP'd, turn up or let me know if your plans have changed.
If you have dietary requirements let me know in advance (like I asked!). Happy to accommodate them but not psychic.
If you want a sibling to tag along, let me know in advance. I mean, preferably leave them at home with their other parent, but if that doesn't work then just a bit of notice would be nice.
If you bring said sibling along and they are a whiny shit who pushes to the front of the queue for cake and then chases the host around for 20 minutes mithering for a party bag, stop chatting and try to distract/control them.
Please don't recycle wholly inappropriate presents - you know, I know, and even my five year old knows.
Why the fuck do apparently reasonable people act like this?
