@ Arjuna: Well actually, at the library I work at there is a piano in the back room that they let me play any time I want. Sometimes people overhear me and come in to listen although after they come in and say "That was beautiful! Play something else!" I'm always at a loss of what to play next.
Last year I was invited to come into the music history teachers class in my school and play Fur Elise and Rondo alla Turca, I only played the first half of the latter because I was too nervous that I'd keep messing up.
Also sometimes during holidays or family gatherings I play for my family in my living room.
I've gotten a little better than the first time I played in public but I definitely need to get the leg shaking under control -__-
I'll keep working on that..
