My neighbour: "Hi Eleanor, I saw you power-walking yesterday, down at the beach! I waved but you didn't see me."
Me: "Oh, yes, I've started walking every day...sorry...didn't see you.
Me (inside): "WHAT THE??? POWER-WALKING??? I WAS JOGGING, and I probably didn't see you because of the sweat pouring down my face."
But you know what? Disco makes everything better.
