Sil has decided not to attend ds's 21st birthday meal as she concerned about catching covid as she is going to Spain to her holiday home a few days after the meal.
He's her only nephew and we have only seen her a couple of times in the last two years due to her worry over catching covid.
She's not vulnerable nor elderly.
AIBU that's she prioritising a trip she does every year over a family event which will only happen once?
