Watch The Feet

Part of being attuned is noticing body language. When you're telling a story or getting into the weeds about the details, watch their feet. 

If they're angled away or their shoulders begin to turn down that's your cue.  It's your cue to land the plane.

 If you're having trouble getting people to listen to you it might be because they're scared. Scared they will get trapped in your long-winded  monologue.  Tune into body language and know when to be concise.

Many “talkatives”  mistake politeness for interest.
