Don’t Turn Around

My friend once said to me “Hello there!”

So I turned round and said “…hang on, where have you gone?”

He turned round and said “What – wait a minute, where have you gone?”

So I turned round and said “Why are you facing that way?”

He turned around and said “There you are! Er, what were we talking about?”

So I turned around and said “I can’t remember… hello?”
