The unforgettable experience I've ever had Draft-2

When I studied in the kindergarten, I had a sever accident that I can’t forgettable.
On the way to home, my grandfather took me by a scooter. When we passed though the crossroads, suddenly, the other scooter bumped us, my grandfather and I fell down from the scooter on the road.
At the first, I saw the blue sky in front of my eyes. Second, I looked at my grandfather; he lay on the other side of the road. He can’t move but he can’t talk. He asked me that if I got hurt or not.
At that time, I cried. Not only had my grandfather far away from me, but also many struggled of books. I really took fright. Very soon, the ambulance came. Fortunately, my grandfather and I were got little abrasion, we were safety. This is the unforgettable experience I’ve ever had.
