I was having dinner at a restaurant when Harrison came in. Harrison worked in a lawyer’s office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harrison saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me $2. To my surprise, he gave me the money immediately. "I have never borrowed any money from you", Harrison said, "so now you can pay for my dinner!"
