Dh and I both have dark hair and dark eyes. Ds has dark (ish - will probably get darker as he gets older) hair and dark eyes, and is the spitting image of his father, only more handsome, obviously.
Dd OTOH is a reddish blonde with blue eyes. She is utterly gorgeous (but then I would say that) but looks nothing like me or dh. Which, you know, is fine. But MIL is obsessed with her eye colour and keeps saying stuff like, "Ooh, if she keeps that colouring she'll be a stunner!" WTF? She'll be a stunner anyway you mad cow! Stop banging on about it, it doesn't matter what colour her eyes are!
I suppose I would be less irate if she'd said it once but she says it Every Fucking Time we see her (about twice a month). It's wearing, to say the least.
