Japan - Am I Getting Fat?

I was curious if I was losing or gaining weight while I was in Japan, but didn't really want to buy a scale. So I asked the front desk of my apartment building if they had a scale that I could use. It turned out that they had one and they would get it out of storage and drop it off at my apartment. When I return to my apartment later in the day I found the scale with this note. It made me laugh because the way it's written makes it sound like I'm in desperate need to start watching my weight.
