Please no

I have nothing against singing. I love music and even sing in the church worship team. But sometimes it really grates my carrot when people sing to the radio when they're in company. By all means, sing in the shower, or with your brush in front of the mirror, or in front of your boyfriend or friends, but please please please don't sing in front of me when I'm trying to count money - especially when you can't reach the really high notes and then go spectacularly off key. It's just disturbing.
