We've been learning about the planets. I was totally unaware that Sam and Grace were taking a trip to Mars. I walked into the kitchen, minding my own business, and found Sam rumaging through pots and pans. When I asked what he was doing, he informed me that he and Grace needed space helmets. "For what?" I asked. Because they couldn't breathe on Mars without space helmets, of course. Silly me! He couldn't see out of the pots, so we all came up with other ideas. Their trip to Mars was great fun! I almost missed it. Imagine how surprised I would have been it they just flew off in their space shuttle without any goodbyes?
