I would be mad, but, I’d also say go. Honestly when I was about 19, my mom more or less did this, in short she spent weeks talking up a hair dresser friend at church, commented that she played D&D, Eventually arranged for me to join her, and get a hair cut.

I talked with her, didn’t really go anywhere, From my understanding the girl afterwards kind of responded to my mom something along the lines of “I know you are hoping I’d be your son’s future wife but that’s not where I am in life right now”, and all the embarassment went on my mom for that.

So yeah, if you ask me, give it a shot, if it sucks, you’ve got solid standing to tell your dad not to do that shit again, if it’s good, maybe something good can come from it.
