One thing that flattered me was when I wore this blouse and for some reason this guy said, "you look so goddamn cute" ...although that got me feeling like a little girl and it doesn't flatter me as much afterwards :?/
I think being called cute is one of my favourites! It makes me fell like I need protecting, and the person has taken it upon them!
Um I would like to say something about my personality. But it has to be really thoughtful, not the boring "You are so nice" which sounds so meaningless and empty.
