Taketonbo

When I was writing my diary while having lunch in a coffee shop, a stranger came up to me and asked "Are you a student ?". I answered "No". Since I only answered with few words, he asked me "Are you Japanese ?". I answered "Yes, I'm Japanese". He saw me studying English as I was having lunch, he was impressed. He said "I will give you a reward because you are great". Then he gave me a Japanese toy called "Taketonbo". After 5 minutes he left. I tried to fly the Taketonbo at a small park nearby, but It was difficult for me to play with it. I haven't played with the Taketonbo since I was in childhood. I forgot how to fly it. I tried to many times, but it didn't fly into the sky like how I imagined. I should have learned learned how to fly it from the man.
