是以I was riding my son's scooter home from the library while开头的要带答案

I was riding my son's scooter home from the library while he was accompanying me on his bicycle.I was wearing a heavy backpack loaded full of books.Suddenly the scooter hit a rock and I was thrown from it and landed flat on my face onto the pavement.My concerned son,who is 8 years old,rushed to my side to help me and bravely stood next to me holding both his bike and the scooter as I tried to get up.
I then realized that my front tooth was lying on the sidewalk beside me!I scooped it into my pocket and then probed my mouth with my tongue to assess the damage.Not wanting to alarm my son,I tried to get up and reassure him that I was okay.As I tried to stand,my head was spinning and I felt nauseous so I bent down and put my head between my knees.Cars were speeding past us on the main road,unaware of my little drama.Neither me or my husband own a cell phone (surprising,I know) so I just figured we'd walk home a little slowly.We were about 3/4 mile from home.
As I was pondering all of this sitting on the sidewalk,an older gentleman came up to us and repeatedly asked if I was ok and if he could do anything to help.I asked him if he had a cell phone.He did and I used it to call my husband to drive over and pick us up.Once I stood up I thanked the gentleman and told him I really was grateful for his help.He walked off,but I could see him watching us from a distance to see that we were really ok.
Since I was still shaken up by the incident when my husband came,I did not have the clarity of thought to ask for the gentleman's name or address.Afterwards,I simply thought of him as the real "good samaritan" and I have done my best to "pay his kindness forward" to others.
So,nameless,kind stranger--THANK YOU!And for those of you who take your cell phone for granted,remember that you can use it to help someone someday!
