Haha, actually he was being sarcastic. But it's so funny (and it bothered the other male friends I have who watches FMA).
How did this happen?
He used to think that Envy was a girl...and thought 'she' was very cute indeed...
Until I shattered his fantasies with:
"But Envy's a guy >.>"
Now he is in love with Winry...thank goodness for that...
