Text friends to come out for my birthday on the 16th, just for a few drinks nothing crazy. A few couldn't make it - fair enough. One I assumed couldn't make it because she was working.
It turns out that she is not working but is instead staying at her sisters house because her sister hates being in the house by herself.
They live about 10 minutes from each and see each other a lot anyway, the sister is engaged and lives with her partner (he is having a boys night on the 16th) and she also has two daughters who lives with her. The sister is also 32 and does not have any SN or anxiety etc. She just generally doesn't like being in the house by herself (even though the children would be there)
I don't like staying in my house by myself, but I am a grown adult and if it comes down to it then it's not an issue.
aibu to think this is a rather pathetic excuse??
