I (23F) graduated college last week, and me and a few friends planned this small road trip to celebrate. Nothing crazy, just four days driving along the coast, staying in cheap Airbnb’s, eating good food, taking pics something we’ve talked about doing since sophomore year.

Everyone chipped in, we saved for it, and it was meant to be one last trip before people start moving away or starting jobs.

Anyway, two days before we’re supposed to leave, my sister (32F) calls me kind of freaking out. She’s got three kids under 7, and her babysitter canceled last minute.

She and her husband had planned a weekend anniversary getaway, and now she wants me to stay back and watch the kids. I told her I couldn’t. I’d already paid for my part of the trip, I was really looking forward to it, and it wasn’t something I could just drop last second.

She got super upset and said I was being selfish and immature, and that I don’t have anything important going on and she never asks me for help (not really true, she does, a lot). Then my mom chimed in too, saying I should be there for family and that my trip could wait. I told them I wasn’t trying to be mean, I just wanted to do this one thing for myself after working my ass off for four years.
