When very, very young, I got in the middle of one of those "well, yes, I have a girlfriend back home but we've agreed I can date but I have to tell her". So he met me, told her, and then suddenly the high school girlfriend back home wasn't so cool about her boyfriend dating anymore. I wish I could say I nope'd on outta there cleanly but it was a good education on relationships.
Spoiler alert: He never ended up with her either, apparently, so I guess it was a good education on relationships for him, too.
