With twenty minutes left to go on the elliptical machine this morning, I knew without a shadow of a doubt that it was time for us to purchase a new mp3 player. Our current one, bought for $30 off of Heather some time ago, has developed the electrical equipment of Alzheimer's; it no longer remembers that it's supposed to play mp3s as well as audio CDs, and only plays audio CDs when it gets up on the right side of the bed that morning.
