that people should rsvp

[darwin]

to my dd invite to her party? don't know who is coming!!

oh, well done for remininding me that I have not RSVP my cousin. Got the wedding invite last week and have not done that yet.

And no, YANBU, how can you plan a party when you don't know who is coming?

Yanbu. rsvp is on invites for a reason. need to plan numbers for party bags, food, etc.
Also really annoys me when you invite a child and the parent/granny turns up with another 2 kids in tow and does the 'know u won't mind them staying too..what's an extra 2?'
