I know AIBU but hear me out.
Further to my MIL post last week, SIL is now being a PITA.
She is coming to DD's christening at the end of the month but her H is not and the excuse they gave was that he was having a second stab do (they got married in February) at his golf club. Apparently he had checked if it could be moved and it couldn't so, with regret, he can't come. Fine.
Until... up pops on Facebook last night, photos of him with the caption "second stag do at the golf club". She posted them, knowing I'm her friend, as he is not on Facebook.
I'm poised with a PA comment of "oh so the event COULD be moved, shall I book one more place at the Christening or do you want some time to think of another excuse?".
I mentioned it to DH (it's his sister) and he just said "maybe he's having loads of stag parties". But unlikely tho isn't it, that he'd have more than one with the same group of friends when he's already been married three months.
Please talk me down off this ledge because I'm pretty close to brining down a shit storm.
