My nephew is turning 1 in a couple of months and my sister and BIL are having a party for him at their house which is 4 hours drive from where we live.
DH and I have decided not to go as we're staying with them 3 weeks before the party and don't want to make the journey twice in a month. It's expensive/tiring to get my family there and not how I want to spend my weekends.
As the party is over a bank Holiday weekend the rest of my family are attending (aunts, uncles, cousins and their kids) meaning we will be the ONLY ones not going which my parents are horrified at and have stated "you have to go".
We have considered changing the weekend we go to stay with sis & BIL to the weekend of the party to attend but we really won't get to actually see much of them if there's a large party on which defeats the point of us visiting.
I am close to my sister but they don't come to ours for our child's birthdays so I don't feel like this is the big deal my parents think it is.
AIBU to not go?
