This is most useful when you're asked something you'd rather not answer at that particular moment. Or perhaps you want to ask a specific question, or you're simply in a state of comatose boredom or that someone has asked you a question that's completely none of their business. There are many interesting motives for wanting to change the subject of conversation. Your motive might be "just because." :)

It's not that hard and usually people don't mind a change in the subject. You might be doing everyone a favor. To begin this tactful conversation maneuver, make sure you're listening closely. That is an inherent advantage introverts share: introverts are better listeners!

First, listen for your cue to segue (pronounced "seg way".)
