let's be honest.
It's a whole package thing.
You could meet the most interesting person in the world, but if there is -zero- physical attraction, then a romantic relationship just 'aint gunna happen.
On the other hand, you could meet the most attractive person in the world, but if he/she is seriously mentally/emotionally deficient, a romantic relationship is out of the question. (Tho' some of us would probably still sleep with them, given the chance.)
