Not really that mysterious.

This is where Little Pink Socks comes from. Also here. It has absolutely nothing to do with my little Sprout even though she does on occasion wear pink socks.

I think everyone needs a little pink sock in life. At least one, anyway. I believe life is full of little pink socks, but sometimes you have to look really hard to recognize one when it comes your way. Little pink socks aren't always little, pink, or socks.
