I was having a conversation with a friend the other day, and talking about some parenting stuff. I was describing feeling a bit protective of Jafta in a certain scenario, and she said, "Well, of course you do. I mean, he's your flesh and blood. That's the mama instinct." And then we went on talking, and it took me a minute to register that what she had said was not, in fact, true. That he is not my flesh & blood, but that my friend so perceives him to be that she didn't even catch the innaccuracy of referring to him that way.
And I love that.
