Yellow Dog in the huff

“I thought we were going to the Tesco superstore today.”
“Plans have changed, “ I said. “We’ll go another day.”
“I’ve been sitting here since Sunday.”
“What about your friend?”
“She’s no friend of mine. We’ve split up.”
“I’m sorry to hear that. I thought she was good for you.”
“You have no idea what is good for me.”
  Probably not.
