since when???

[Accord Man]

nor do I want to be disappointed knowing that they're already in a relationship

I think thats what it is.. A protection mechanism ..

And about looks, well thats what you see first.. So you're first judgement of a person will usually be based on that..

I think people would walk around with their IQ/EQ numbers on their foreheads, then you'd base your judgement upon that aswell..
