talk someone's ear off

I’m a dork and not fun at parties and would talk someone’s ear off about a weird public policy nuance, and probably to get away from me they’d say you should run for office.

As a scrawny, bookish and misfit middle-schooler, I was always the last picked for the team but equally first to talk someone’s ear off when it came to film production, special effects, storytelling, fantasy, sci-fi and the like.
