I tell you, it's hard sometimes though! I live with one. I'm just puzzled and marveling at the tastebuds of a person like that. Usually it's how they grew up I suppose, exposed to lots of vegetables and without any sensory issues against them. (I have LOTS of sensory issues against them . . .
And if that's not enough to evoke envy that they gravitate towards vegetables, usually these same people have a natural aversion to fattening foods - sweets, greasy stuff, starchy stuff.
It's just not fair!
