The Death of Imagination

I often used to sing while doing hotel cleaning, or, oddly, while waiting for things to titrate in the little cold-room-trailer in the chemistry lab. Though there's a problem with running out of breath, if you're cleaning baths and suchlike. Never got anyone else to join in though... I don't know if there's really a shared body of songs that people can use any more. I mean, my grandma (and many other people's grandmas, no doubt) used to sing hymns when she worked, and my mum would wander around singing folk songs, so I usually revert to one of those, but I don't know that that any of my coworkers would have known the words (and I generally only knew a few lines myself).
And people don't half look at you funny when they catch you singing. It's a shame.
