I'm ashamed to say it...... violin.
And I was BAD at it. I didn't practice, so when an actual song came on, I didn't know anything.
Anyways, one day, I was sitting minding my own business. Then my crazy teacher told me to come over, so I naturally came over. He told me I was kicked out, something about goofing off, and something about a sandwhich. To be honest, I think he noticed my bad skills and needed to find a way to kick me out without hurting my feelings. Not the best childhhod memory.
