Potential

When you meet someone and begin to see them as being more than a friend how do you rate their 'potential'? Do you see it in a very pratical way, basing said potential on cold, hard facts?
(ex: has a good job=can support me)
(ex: great bone structure, fabulous green eyes=will make beautiful children)

Or are you more of a romantic optimist, judging potentiality based on how they make you feel when you see them?

(ex: you get nervous butterflies in stomach upon sight of said person= this feeling will never wear off)

(ex: well, s/he tolerates my incessant ramblings about how the Boston Red Sox really are cursed/clothing I made for my cat/my collection of clown figurines*= they must love me)

I strive for the something in the middle-that they have a stable job that does not leave them miserable, and my children's father have straight hair so that at least my kids will get a fighting chance in humid weather. There is something to be said for meeting someone whom I like to be around and feel a slight longing upon the date ending (not in a stalker-like way, but in an I-want-to-stay-up-and-talk-with-you-until-4am way).
