Ordering jokes

Once, after a long time, I had a buffet with her, and we used to exchange food with each other. That day, she gave me a piece of tofu and said, "Come, eat my tofu." I looked at my plate and there was only one piece of meat (sliced), so I gave her a sausage and said, "Come on, eat my sausage." A second later, I didn't know what it was, and she began to laugh wildly.
