"Where'd that blonde hair come from?" Complete strangers ask me all the time. They take one look at mine and Nate's medium brown hair, Dustin and Evan's dark brown hair and then at our blonde hair, blue eyed baby girl.
"Well," i usually say, "My mom has three blonde sisters and most of my family has blonde hair."
And when we were down in western, Ky for Thanksgiving, i made them all go out in the cold so i could get a pic to prove it. :)
