DD1 has red hair. DH and I both have brown hair, although mine does have reddish highlights in the sun. I like when people compliment the hair, but I always grit my teeth when they ask where she gets it. I hear that question all the time and it gets tiresome answering it so often. I know it is a minor thing, but it does drive me up a wall.
I hate sizing inconsistencies as well, including vanity sizing. I know wearing something labeled two sizes smaller than I am doesn't mean I am smaller, but the clothing is cut bigger.
