Hi Jake! Thank you for sharing this wonderful story. Here are your corrections. ^_^

I can play the guitar a little. When I was in high school, I joined the guitar club. The reason why I joined the club was so simple. It looked very cool to me. I saw my senior who plays the guitar. It was so impressive for me. I decided to sign up in the guitar club with my best friend. I learned how to play the guitar from one of the seniors in the club. He taught me the basics. It was a good experience to learn how to play the guitar in my school. Sometimes we did guitar performance on stage. It made me so nervous to play the guitar in front of the audience. I made mistakes while performing. I reminisce that event with a smile. Actually, I didn’t practice the guitar that much. I liked to hang out with my club friends. That’s why I’m not good at playing the guitar now. But I participated in the club activities a lot. I continued to be as a club member until I graduated high school. Now, I just play the guitar once in a while and I miss that time so much. If I could go back to my high school, I would practice harder than before.
