Last Sunday I was in work by myself and it was a quiet shift so I started playing music on my iPod and started singing along. There I was, harmonising gloriously, when one of the managers pops his head around the door.
Then, tonight, he comes up to the office and says "no singing tonight?" and then TELLS THE REST OF THE OFFICE ABOUT WHAT HAPPENED. IS NOTHING SACRED? I THOUGHT IT WAS OUR SECRET!

I'm a cross between mortified and in hysterical laughter, waaaaahhh whhyyyyyyy?!
I don't know what it is that's so embarrassing about someone walking in on you singing?!
