My sister's bf's son is graduating and somehow my entire family feels obligated to go to the whole shindig. I'm a little annoyed because when my stepdaughter graduated a couple yrs ago nobody in my family even seemed to care. She's my actual stepdaughter not just a bf's kid. I will just be coming home from an out of state vacation and just don't really care to go. I've only been around the kid a few times at a family gathering. Opinions?
