Ok so it's my DD's party tomorrow, sent the invites prior to the holidays. A couple of non-RSVP's (don't really care) but asked her to ask her friends this week just as a reminder and apparently one of them didn't get an invite (her name was on the list but may have crossed it off prior to writing the invites to whittle down numbers but due to a couple of 'can't comes' there is space for her). Anyway, do I send in an invite today with a note saying 'sorry for the late notice and I appreciate it if you can't come'. Or just not? DD's not bothered but she said she'd like it if she came (about 13 kids in all so not a whole class but not an intimate one either). Anyone?
