Maya and Anya were sharing a room, or at least sharing the bunkbeds I'd made.
I come in to the room and find Anya up on the top bunk (Mayas bunk) making the bed.

Me: "Honey, why are you making Maya's bed?"

Anya: "Maya says she hates having a little sister, so I'm doing this to make her happy."

Melissa and I almost cried.

Not bad for a 4 year old.
