Most of us have at least one intense interest we enjoy sharing with others. When discussing your interest how tuned in are you to when others have tuned out?
Though using "tuned in/out" in the question might be groanworthy coming from me, it's still an apt image. Even my wife and daughter sometimes get that "I'd rather be somewhere else" look when my riffing about music has gone on too long. When was the last time you saw that look? When was the last time you felt yourself giving that look? Do you think the other person had any idea you had checked out?
When I'm the recipient of this mild torture - instead of the torturer- these situations often start out as a capacity issue, like getting a delivery of furniture suitable for a fourteen room mansion while living in a studio apartment. I might enjoy looking at the furniture for a while even if I have no good place to put it. But if more delivery trucks continue arriving or the furniture begins to look unappealing, capacity ceases to be the main issue. Your experiences with all that furniture?
