Arranged to go to the theatre with sibling last week.
The play was cancelled at the last minute by the theatre so the theatre booked us on for another performance of the play tonight.
I texted sibling at 10 this morning to ask if they were still coming - they said yes.
I then texted them half an hour ago and they’ve just rung me to say they’re not feeling well and can’t go anymore.
AIBU to find this really unfair of them? They haven’t apologised. I find it really last-minute.
