Last night my partner and I were sitting on the sofa. He noticed something on his hand, said "Oh, what's that?", picked off a scab, ate it, and carried on talking.
I said "Did you eat that?!"
He said "Yeah. Everyone eats scabs."
I said "Yeah, if you're five!"
I kind of couldn't get my head round it, and couldn't kiss him all night, until he'd brushed his teeth!
