When I approached him, again he waved his hand asked, "Wanna ride?"
I smiled to him and said no, but instead I hand him over a printed photo.
He observed the printed photo, then he was being excited saying, "This is me on this bench... how could, when did you take it?"
"You certainly have forgotten, don't you remember?", I said.
He silenced for a while, then said, "Ah yeaa, I remember of course"
Then he smiled looking at his printed photo.
While looking at his printed photo, he told me that he is at his sixties years old, and lost all of his tooth.
After I listened to his story for awhile, I thanked him and farewell him.
Duh, I forgot to ask his name.
