parachute jump with my elder sister

When my sister and I were very young, we lived in a bungalow. There were no children at the similar ages of us in our neighborhood. As a result, we had no choice but to play with each other and we became bored of many games and we tried to think of more new games. One day, we watched a TV show about the parachute jump and we came up with a new idea: using umbrellas as parachutes, we could do the parachute jump on the roof of the bath room. At first, I felt scared and refused to jump before her, so she encouraged me and suggested jumping together. Gaining more courage, I climbed up to the roof with my sister. Then we were standing on the verge of the roof, both holding an umbrella tightly in hand. “So I say 1, 2, 3, jump! Then we jump, ok?” said my sister. “All right.” I promised. I took a deep breath and jumped down the moment my sister shouted 3. However, she didn’t. At the beginning the umbrella could still support my weight but as I speeded up, I suddenly felt it break down. The wind blew heavily beside my ears and my mind became blank. Finally I reached the ground and managed to stand steadily. I could feel a sharp pain in my ankle. And then I turned my face up to my sister,smiled and said, “It’s really exciting, try it!”
