Some background: BIL and DH don't really get on but speak on the phone about once every month. They have one child who's 2 and a half.
BIL and SIL live about 3 hours away from us. We went to her Christening about two years ago but haven't seen any of them since. We send them all presents every Xmas and get their DD a present for her birthday as well.
Now BIL and SIL have sent us an invitation to a 'Christening Anniversary' for their DD which is basically a party to commemorate when their daughter was Christened.
I've never heard of one of these anniversaries.
We haven't replied yet but DH spoke to MIL last night and she thinks we're BVU to not go and not send a present.
What the actual fuck?
AIBU to think you can't just invent random occasions and expect people to rock up bearing gifts?!
