My OCD comes out

I was masquerading as a teenager, hanging out with a bunch of kids who were trying to start a band. We got invited over to play for this older (40-something) Indian guy. But I was found out - a girl asked me, how old are you? When I told her to guess, she said 25, and I said, you got me (when really I'm close to 40...). Anyway, as the rest of the band was chatting with the Indian guy, I noticed how filthy the keys of the keyboard were, and I started wiping them with a Wetnap. The Indian guy called me out again, but I just had to keep cleaning it. While I was cleaning, they actually started playing music, so I was left out, but I was very happy when the keyboard was finally clean.
