^ Some people are interested in eye colour - I, for one, seem to take note of it. If you look from far away, CC's look brown... that's what I think, anyway... people just want to be sure... I don't know.
I know you're sick of it... but not everybody's eyes are just blue or brown, which is really easy to pick out.
I don't even know what my eye colour is anymore. I used to say green, then I was saying green/blue, and now I have pictures of me with blue eyes... and I'm thinking, "Hang on, I swear they were green before!"
