Daddy plays the best games.
When Mommy plays Lego, it goes a lot like this: sort the Lego back into the right drawers, rebuild something from the directions, help find missing pieces. (And hey, I can build nice square houses, too - with a door and a window).
When Daddy plays Lego it goes like this: spend two hours assembling characters and staging them throughout the downstairs of the house, while fending off questions and keeping a six- and three-year-old engaged in the preparation and focused on what promises to be something Really Fun when it is all ready. Then spend another hour on a very detailed Quest based on the arranged characters and a big story conjured up in Daddy's head. This one involved pirates, a bicycle, a "horn of sleep," a wizard, "crabby gems" and a protagonist who could talk to animals, among other things.
All this plus a sleeping baby meant Mommy had some time to get things done, and everyone had a good morning.
