Shallow Zac

Within the first few seconds of meeting a girl, I decided whether or not I am attracted to them... or will be attracted to them.... Does that make me shallow?

Dont get me wrong... physically attraction is by far not the only way that I sort through whether or not I would like to take a girl out... Eventually, personality, sense of humor, general disposition towards life, and such things take precedent... but at first, physical attraction takes precedence. And just so you know... I am not talking about comparing girls to some "ideal image of beauty". Rather, I am just talking about whether or not "I" am personally attracted to them.

Is that such a bad thing? or am I allowed to be a bit shallow at first?
