It is not clear whether Rose understood it was her birthday, but she had a good time at her party. Bounce house, friends, cupcakes, crafts, juice.... (juice is Rose's favorite thing about parties).
Rose was a little uncertain about the candles, but quite sure about the frosting... which she ate and then handed the "bread part" (as Jack calls it) of the cupcake to Daddy and asked for "'nother haf" (we split them in half for sharing flavors).
