Playing the Guitar

"Teach me how to play the guitar" I said to my sister (Zion). "Okay okay so you can stop begging" Replied Zion so we went down stairs and played the guitar. She had a guitar and I had another one. I told her to teach me how to play "Stand by me." So she played it and played it but it was too hard so I just know how to play the first bit of Stand by Me.
