This is what you do when you're 12 and it's summer...you sleep in a tent in your backyard because you can. You also bring in a ton of games, flashlights, snacks, sheets, pillows and writing paraphernalia. The girls had this thing up all by themselves in under 15 minutes. Impressive.
I love that these two still have a such a huge, active imagination. They create worlds and ideas and join each other in them. That's the beauty of a tent in a backyard....it's a whole new world to enjoy if you have a big enough creativity and someone to share it with.
