My dad is in town today. He arrived yesterday, in time to spend most of the afternoon pushing on the girls on the swings in the backyard. It's only 8:30 a.m. and already he's explaining the concept of cells to Hannah. :)
He can only stay until tomorrow, but I'm hoping he'll answer some of her other hot-topic questions, like "How does electricity work?" and "Is magic real?" before he leaves.
