We were with a group of people that don’t know us very well, it was my two boys and I.

random parent: “What’s your brother’s name?”

thing one: “He’s not my real brother.”

me: “He seems real enough to me.”

random parents giggle

thing one: “well, we don’t have the exact same DNA.”

random parents are impressed at his big words

thing one (feeling pressured to explain himself): “We didn’t come out of the same person.”

Ah, all clear now.
