My DS is having his birthday party at a bowling place soon. I have to give definate numbers (and pay for them) by Saturday. Invitations were given out before xmas with a RSVP date of this Tues (first day back at school) and my home and mobile nos on the invite. All the invitees have replied or been "chased" and are coming except one. X's mother doesn't do school pick up/drop off and hasn't replied to the phone message I left her.
Should I assume X isn't coming if I can't get hold of his mother to ask or assume he is and pay for him and possibly end up out of pocket? WWYD?
