Memory is a strange thing.
I'm reviewing the instructions for my smart phone, partly because I'm going out of town for a few days and I'll be using it.
I get to the part about Switching between calls, when a second call comes in. And immediately I remember the only time that's ever happened, at least 5 years ago. And where I was at the time, the Flushing YMCA, and where in the building I was at the time, 30 feet from the door.
Come to think, I didn't have a smart phone then. The instructions for the smart phone seem to have three steps instead of one, like the simple phone. .
