Every single flaming year it's the same sodding thing - send out DD's birthday party invites well in advance as it's straight after the Easter break and I know a lot of families go away for the Easter break, then spend the next frigging month chasing and chasing, emailing 3, 4 times, texting, Facebooking, ringing mobiles and house phones... FFS!!! Every single sodding year! I need to plan party bags, food, cake, I'm limited to numbers and if some can't make it I need time to invite others, I have to confirm numbers with the venue and pay the balance, and I don't want to be frigging doing it the day before the effing party, not to mention that every year I have a little girl desperately asking me who is coming whilst I'm having a sodding breakdown secretly in a panic that the 3 replies so far are all that are coming and I'm going to have a heartbroken birthday girl on the day!!
It's so bloody rude! 
AIBU to think it's actually quite a privilege to be invited to a party and that if a mother is paying out for little Johnny or Suzie to come the least one can do is fucking reply, especially when the invites very clearly say please let me know as soon as poss?? I sent the invites nearly 4 weeks ago!!!!
So bloody rude! If it wouldn't guarantee no one would come I would send out a "FFS you rude bitches fucking reply or your brat can fuck off!" 
Sorry, just seriously pisses me off. I don't need the stress.
