I listened to her complain for a while and asked her if she wouldn’t rather come to Europe with me rather than waste away her summer there. She answered that she would, agreeing finally and at the last minute to come. I laughed at her. I didn’t believe she would come.
Propose a thought experiment. Your mind goes dark places when you let it.
