wow, have you put on weight?

Tonight, I was talking to my friend about how I was trying to gain weight.  He asked me what happened that I had lost so much and - being open about what I've been through - I told him I had been working on recovering from anorexia.  After explaining (the short version, of course) and telling him that I was now working hard to pull my weight (literally) on the physical end, he replied with, "Wow, I had been thinking you'd put on a little weight."

"Really?"

"Yeah, it looks like you've gained a few pounds!"

That, my friends, totally made my night.  I felt like most women seem to feel when their friends tell them, "Wow, have you lost weight?"

Does anyone else wonder why the number of women trying to gain weight doesn't balance the number of women trying to lose?  That always bothers me.
