You say no, wait, I'll take you! and run to the bathroom for a few supplies. You patch his leg up with some gauze and medical tape and hop in your car together. You drive him to the local emergency room and sit and wait with him. Meanwhile, your mom and siblings have been notified and show up in the waiting room too, shortly after your BF, who lives over an hour away and was already on his way over when you had to take your dad to the emergency room.
Dad is doing pretty well, though impatient. Bleeding has mostly stopped and he's been waiting over an hour so he's bound to be seen soon. Its pretty clear he'll need 1 or 2 stitches, which doesn't bother him, he just wants to get it done so he can go home and get back to work. He now has his wife and other kids to wait with him. You ask him if he minds you leaving to keep your plans for the day with BF (which have been put off) and he says no so you leave. You obviously see your dad later that evening and ask him how things went and he's doing fine.
Was it inconsiderate to leave instead of waiting for dad to get his stitches and be discharged? Rude? Selfish? Something else?
I did this to my dad almost 10 years ago and I just found out that at least my mom thought that me leaving was *not cool*. I am totally willing to accept that I was being a thoughtless teenager but I am honestly not really finding anything inherently awful about it. My dad is pretty no nonsense and it wasn't really a scary experience for anyone...I had thought. I'm torn because my mom and I have/had a pretty tumultuous relationship so part of me is trying to just brush it off but I don't want to not do any self-reflection and miss the opportunity to make a different choice in the future.
