Dear Jack,
I was your age when I was learning to play the guitar. Obviously, I still play and continue to write songs; which I record and publish on my YouTube channel.
Your entire life, I have reminded you: “Once you are ready to learn to play the guitar, you get free lessons from me!”
So far, you haven’t taken me up on my offer.
I was happy to see that you at least enjoyed learning a few songs on the ukulele during music class at school.
Maybe in a year or two, you’ll be ready for my award-winning free guitar lessons!
Love,
Daddy
