When I walk to work, I frequently listen to music (on the fantabulous iPod a whole slew of people got me for my bday, coordinated by the wonderful Shayde.) I usually pick some jaunty selection for the morning, kinda a peppy start to the day. And I leave my apartment humming softly along with the music. Somewhere along the walk, I start to realize that I'm humming louder, and soon after that, I'm singing, and pretty soon, singing full volume -- not belting, but singing in a normal voice -- and getting funny looks from other people on the sidewalk. The whole process just tickles me.
