AITAH for not wanting to travel cross country for a high school graduation on my birthday

Pretty simple, I didn’t commit to going to this event. Family made the assumption I was coming. Immediate uproar about me not going. Event takes place on my 25th birthday and I would need to travel from the east coast to the west coast the day prior to the grad and then travel back the following morning because I refuse to take more PTO.

Keep in mind, my own grad school graduation is the following weekend and if I’m making that kinda trip out it’s certainly gonna be for my masters graduation and not a high school grad.

So, AITAH? 😭😵‍💫
