Public singing face.

I'm going through a public singing phase at the moment. Not in a torch-singing-in-smoky-bars kinda way, or even a karaoke way - just in the sense that when I am walking home with a full bag of groceries or checking the mailbox, I suddenly feel compelled to break into song.

I've been caught out a few times. Walking home in the dark last night, singing under my breath, I passed a couple of people smoking out the front, curled languidly against each other on their shadowy front porch. I didn't see them at first, just had the vague sense that someone was watching me, and quickened my pace. When I realised that no-one was following me, I felt slightly foolish. When I realised that a couple of people had just witnessed me warbling Fiona Apple's "Paper Bag" and swinging my handbag in a vaguely choreographed manner...

I'm not sure where the urge to sing on street corners comes from, but I find I'm indulging this particular whim a lot more these days than I did a couple of years ago. It makes the trip home from the supermarket much less tedious, and sometimes I just want to sing. I don't know. Do other people do this? Is it common?

And if you run into me in the street, will you join me in some sort of ridiculous duet?
