I was lucky in that when I was growing up I got a musical instrument almost every year for Christmas, and sometimes not your ordinary instrument. I've had a melodica and an autoharp. The melodica is basically a keyboard that you blow into, and the autoharp is a triangular-shaped stringed instrument that you strum, made famous by June Carter Cash, I think.
Anyway, I also got conventional instruments like a piano and a guitar. I played the piano by ear for years, but never was able to get the guitar thing down, mostly because my fingers would start hurting before I could figure it out! But I always wished I could play guitar, even when I was playing piano, because the guitar is a much more portable instrument!
