I'm also relearning a sonatina by Diabelli that I used to be able to play all the way through. Much longer piece with different sections/movements/whatever you call them. Diabelli is much more light and happy in tone. He's a good antidote to all the Chopin.
The best part of this is the mental break it offers. I come home for lunch, eat, and zip through a couple pieces. After I'm done it's like I've taken a mental bath. My mind feels clearer and I'm more relaxed and in a happier state of mind. I think it's because I have to focus so much on my playing that my mind just ejects any extra baggage sloshing around in my skull.
One thing I've never done is play in front of anyone. Jim hears me sometimes, but he's not really listening, and I really try to practice as much as possible when I'm alone. In fact, I'm not sure I could play in front of someone. Maybe when I get a better handle on some of these pieces. For now, though, this is a very private thing.
