It’s not public knowledge beyond my closest circle of friends and family, but I rather enjoy hacking at the piano. Nothing technical, nothing formal or rigid, just relatively freeform music. Piano is one of those few instruments that can take you somewhere else. You sit down with a decent glass of wine and forget the world and its then distant problems. Doesn’t matter if you’re any good; you just play.
When I came to college, I never realized how much I’d miss the old upright grand my parents had restored at their home. I used to play on it for hours. Our whole family tree (cousins, grandparents, you name it) is very musically inclined and I probably fit somewhere in the “okay” range. Still nonetheless, I enjoy it.
