You really do learn to play the guitar, though I think she would do better with a 3/4 electric. She'd only want it if it were rainbow or pink.
I once asked Bry-D to teach me to play the guitar. He wasn't sure how to do it, because for him, music comes naturally. It's a part of who he is, somewhat because he learned so early. Just as sewing is something I can just do, he can play most any instrument, and don't let him tell you differently. And so, Eliz is learning. I don't expect her to play for other people, or to be in a band, but she comes from a few generations of musicians, so she's expected to learn. I do look forward to watching her jam with her father.
