Why did I just do that?

Why did I try on a pair of jeans that I know are tight?  And why did I look in the mirror and see most of the 30ish lbs I have gained in 2010 all on my thighs?  Well, it's not all my on thighs but I swear at the moment every  pound was there!  It put me in a sour mood for a little while.  I seriously just wanted to stuff my face.  I hate when I do that to myself!
