Qualified Perceptions

Oh, I know I'm not obligated to discuss politics with cold-callers. :) I'm defining "blowing off" as ducking out of the conversation that the other person wants to be having, regardless of who it is or how reasonable it is to do so, or how polite I am in doing so.

I don't feel bad blowing off people who want to sell me credit card insurance. I don't feel very bad blowing off panhandlers. I do feel bad blowing off friends. Same verb (for me), just different levels of acceptability.

(Your version of the verb is more like "duck out rudely"? )
