Kev: Scales aren't that accurate.
Me: No, I'm using the Wii Fit, I think it's pretty good.
Kev: Putting it on different surfaces can change how it works.
(quiet horrified pause, as I realize that since moving to the new house, I've been using it on a high-pile IKEA rug, instead of on hardwood)
Kev: You didn't think it was suspicious when you suddenly lost ten pounds?
Me: (pathetically) No? (It happened during the move, see, and I was hauling a lot of boxes around and exhausting myself and suddenly going up and down all those stairs -- you could lose ten pounds that way, right? Without noticing?)
Kev: (pitying silence)
So this morning I braced myself and moved the Wii onto the hardwood, and what do you know -- 9.5 pounds came mysteriously back. The Wii thought I was carrying a small pet or something. I have just gained a small pet's worth of weight. Argh.
Oh, I haven't really. And in fact, I've still lost weight -- just not nearly as much as I thought I had. Basically, I gained five pounds over the slothful winter, and I've lost those again, so I'm back where I was at the end of last summer. Yay, I guess. I think I need some tea.
