feeling listless

Sounds Whenever I'm at the supermarket with my parents, we always get separated. I'll be off in the bread isle when they'll disappear into the frozen food. The only way we'll ever find each other is a whistle -- a paticular whistle we only know. My Dad's is the best -- it's loud and turns the heads of all about. By comparison mine is a whisper -- they need to be an isle away before they can hear it -- sometimes just in front. I thought it was just us. But it seems many family have some way of communicating over long distances. This month's Lost and Found sound is 'The Loon Call' a whine which radio producer's Brent Runyon's family have used for generations to call each other to dinner -- which he unfortunately can't replicate. Can I relate...
