Back when I was at university, I was in the band, and there was one guy in my section that was super annoying, and who couldn’t talk with a person without squaring up to them (and then talking at them).

One time my best friend (also in the section), in the middle of the guy’s sentence with a bored expression on her face just… turns and walks away as if he had stopped speaking.

The rest of us were thinking “wait… we can do that? I didn’t realize that was an option.”
