Not every argument starts with, 'Hey, wanna take this outside, buddy?'
Sometimes it starts with a question or some other conversational gambit.
My friend Corrie says you don't have to accept every invitation to the dance.
To follow this, you have to know you've been invited to the dance.
Here's the tip: look at their shoes. If they're wearing dancing shoes, they wanna dance. It does not matter what they say.
How do you look at their shoes? Ask yourself: Why are they saying this / why are they asking the question? You'll know pretty much straight away.
How else can you tell? If, when you are reading or hearing their contribution to the conversation, your blood runs cold or starts to run backwards or you feel under attack, they're wearing dancing shoes. Sit this one out.
