Took out guitar today

I checked my old school books and notepads today. I'v kept all my old books in one almirah, even my first standard books. I read some of my letters that i wrote some 20 years ago. I also saw the drawings and sketches of imaginary creatures that i made when i was just a small kid. I also saw this guitar in one corner. I decided to take it out, cleaned it and tried my hands on it. I couldn't play anything. I'll practice in free time.
