Potentially embarassing, yes? I'm on my own in my bit of the office at the moment and thus am liable to being unself-conscuious then suddenly discovering someone's walked into earshot.
In other news a couple of days back I was wandering along a remote rural road in Scotland, got carried away listening to what I was listening to and started dancing around the road in a ridiculously over-the-top manner. I was pretty confident no-one would come along but would have been terribly embarrassing if they'd done so. In the end the only net result of this dancing was that the Scott 4 CD I had in my pocket fell out, rolled across the road and down an embankment which I had to climb down to rescue it.
