Hey all, not a storyteller so apologies if the post is a dry read. I'm on a family trip for a week. Was out drinking with the family, and when we got the bill I said I wanted to stay out a bit later and try and make friends. Sister decided to stay out as well, and I let her know that I was completely comfortable at a bar on my own. I ended up making friends, and when she left I told her to find a way back on her own because I wanted to stay out a while. Mom and sister are pissed that I didn't escort her back. I figured since she is an adult (20 years old) she'd be more than capable of getting home safely without my help. Am I an asshole?
