Men of reddit, how did you deal with overprotective or disrespectful fathers when coming to pick up your girl?

Not a dad, but his kid. My boyfriend said he was surprised by how nice my dad was and that he was super nervous he was going to do that thing where the dad threatens the guy.

“Yeah he knows I’ll get to you long before he ever could. He doesn’t need to.”

We’re married now and they have a nice relationship.
