It's DS's birthday party next week and I sent out the invites a couple of weeks back, requesting they be replied to by Friday last week. I work full time and today is the only day I can get out to get everything I need for the party.
I'm still waiting to hear from more than half of them - would I be unreasonable to say tough you haven't replied I'm not going to put your DS/DD on the list at the play centre and am not going to do a party bag for you?
