i said she was fat

i remain mortified that i responded to something like the following -- "i haven't exercised in a while" -- with "yeah, you've gained some weight."  this, i was later informed, is exactly the same as saying "you're fat."  i'm losing sleep over this, but the person in question has taken up yoga with a renewed and vigorous interest and is looking mighty fit these days, so it might work out for the best.  now if everyone would just forget that i said it.
