This afternoon, I planned go to post office to mail out a birthday card. John saw me wearing a helmet and asked me if I am going out by motocycle. He wanted to go out with me if I am going to ride a motocyle. So, we went out...
When we pass through the entrance of a viaduct, he asked me if I could ride him to a "highway". I told him motocycle is not allowed to get on highway. He pointed the direction of that viaduct and said "but mom, there are motocycle in the highway, why they can go there?"
I realized he thought the vaiduct is highway. So, I clarified and told him that we could go there before we went home.
However, I forgot the promise after we came out from the building. He reminded me right after he got on the motocycle. I did not know why he wanted to go up to a vaiduct. What fun would it be?
The vaiduct is designed for overpass a railway, so it is not long. When we went downhill, John started to yell "YE...!". I realized it was fun to him because he never had this experience before... to ride a motocycle and with much higher speed than his bike of going downhill...
