Learning to play the guitar, This guitar originally belonged to my grandpa

When my grandfather died, he left all his musical instruments to me; his dream was always to see me play the guitar. my uncle who came to visit us, took one of the instruments, the viola, and said he would give it back to me when I learned to play the guitar

It's been years since that happened. I still haven't learned, I've been trying recently, but I'm left-handed which makes it a little difficult when I play. I plan to take classes!
