Today is FIL's birthday. Not a big one - 72 or 73 or something, but the PILs are hosting a get-together as is their want, with all their siblings on both sides and some friends etc. Birthdays are a bigger deal in my adopted country than back home in the UK. DH and SIL have taken the afternoon off, and DD(4) will be taken out of holiday club to attend.
I'm 33w pregnant and due to start maternity leave in 3 weeks. Work is really busy while I tie up loose ends before then. I can't leave early as all my holiday is being tacked onto the end of my mat leave.
The party will be from 2ish to probably 6, half 6. I finish work at 5, but I don't have a car and they live an hour+ away by bus. DH could come and get me, but I'd basically be there an hour max, and I'll be knackered and expected to make small-talk with aunties in a foreign language.
So I said I wasn't going. We're seeing them on Sunday anyway, all of us. Now the AIBU part. Some newish friends have invited me to the cinema tonight, the first time ever. I hardly ever get to go cos of DD, it's a 10 min walk from my house. I checked with DH, he said it was fine as long as the PILs never find out, but I can tell he's miffed. AIBU to go to the cinema while gagging off FILs birthday?
