One day in a lovely restaurant Joe and Mary were ordering a salad. Joe put a lot of vinegar on his salad. Mary told him not to, but he still did. After a while he started to choke and then his lips went blue. Mary frantically started to shout for help. Two minutes later someone came over and said that he was a doctor. He helped Joe and when he got home he said the vinegar was too sharp. He and Mary would never go there again. Mary felt proud because she had told him not to put vinegar on it.
