Do you keep it on and pretend not to hear it? or keep it off and pretend you forgot to turn it on?
I'm primarily addressing the bros with SOs.
God forbid, do you actually answer it while you're in the room???
I have a fairly bad track record of hearing the phone any time I'm out walking around, so I keep it on and call back later once i "notice" i missed a call. But I can't help wondering if there isn't a better solution, or at least if i should vary my approach somewhat.
