We are trying to organise a family holiday. I suppose we do a family holiday every 6 or 7 years. The plan is that in Sep 2012 (so 18 months ish time) me and DH, Mum and Dad, Aunt and Uncle and my brother and his girlfriend (and my DC - am currently pregnant, so fingers crossed) go to a villa for a week. Nothing expensive. Everyone is in, but DB and his girlfriend (let's call her Bev) are umming and aahing a bit. That's fine, she is very shy, barely speaks to us and never attends social gatherings. If we are invited round to theirs, she is out, if he comes to us, he comes alone. That's the way she is and that is OK.
So we were never really expecting him and her to come on the family holiday - had booked a large enough villa so they could, but left it open. DB very keen, says they are def coming, what are the dates? We tell him and book it.
Ten minutes later a frantic phone call from DB - "Don't book it!! Wait!!". We have already booked it, he is really upset and says he thinks they will have to drop out. After we told him the dates he checked with Bev, who said she would be on her period that week, and wouldn't be able to go.
On her period. In 18 months time. Riiiiiight.
Now, to me, clearly this is an excuse she has siezed upon. No one actually seriously knows when they will be on their period in 18 months, and surely she'd just get those pills from the doctor if it were true. Now everyone running around trying to rearrange things, when it seems obvious to me it is an excuse and she is going to come up with more and more outlandish excuses if we do rearrange it. DB seems oblivious and is hassling us to change the dates/villa and is getting very offended if you intimate that this sounds like Bev is trying to get out the holiday. I say we let the poor girl off the hook and say no, we aren't changing it. AIBU?
