I'm Chinese, but I live in England now. I can speak English. But sometimes I make mistakes with English words. It was sunny yesterday. My class went to the park. I said, "Let's fly cats in the park." My classmates all laughed. I didn't know why. Then my teacher said, "Cats are animals. We can't fly them. But we can fly kites." "I know my mistake. I wanted to say 'kites', not 'cats'." I said. Then we laughed again. That was funny.
