The girl with the mumble in her heart
She was small for our age but we all ascribed it to the fact she had been born with a mumble in her heart. Sometimes she would let you listen through her T shirt, and though it just sounded like putting a shell to your ear, we knew that we were supposed to be able to hear the mumble and would all claim that we could. Nobody's bluff was ever called, as would later happen in medical school, by being asked to describe what we heard.
“D'you hear it?”
And that would be that.
Back then, having a mumble didn't seem like a bad thing at all. It was a party trick and “a get out of games note” rolled into one. More, it meant that you knew all about the strange and fascinating world of hospitals and had stories to tell about what went on there.
