I'd like to teach y'all a Southern phrase that will help you get off a phone/Zoom/Facetime call or you don't want to be on anymore but don't have an excuse to leave. Let me introduce you to the power of "Well, let me let you go"
Conversation is winding down and you can tell it's time to hang up, but you don't know what to say? "Well, lemme let ya go!"
It works perfectly, almost every single time. It's inoffensive, polite but doesn't leave room for questions, succinct, and not overly personal or revealing about yourself - you don't need to pretend to pee to get off the phone anymore.
