I love, love, love red hair.
My husband's bright red hair is the first thing I noticed about him. (It has faded a great deal by now.) I also had one previous boyfriend with bright red hair.
When my son was born, I was SOOOO hoping he would have red hair. He didn't at first - it was brown when he was born. But it soon turned red, and he has the most beautiful thick, bright red hair that gleams in the sunlight. That's by no means the best thing about him, as someone pointed out upthread; the fact that he is a genuinely nice person makes me even happier.
His friends called him ginger in high school. I have video of his graduation, and someone shouting "ginger!!!" when he crossed the stage. That term is not as common in the States as it is across the pond, and I thought it was pretty funny.
I do love red hair. 🙂
