If mom is old

Mother took me to play in the lake park. Walking halfway, my feet hurt very much. I will let my mother take me a while. As the mother walked, she said, "If I am old, would you like me to carry me like you?" I said, "Yes." I said, "I have to study hard and become an inventor in the future. I personally made a pair of shoes that would fly and let my mother put on it. Wherever I want to go, I went there, no effort at all, and I was not afraid." My mother listened to me and smiled happily.
