My son's, that is.
For two days he has been babbling and bugging me about a mouse, and traps, and "can I borrow some cheese"? I've been occupied with cleaning, clearning and organizing so I've largely brushed him off. "No. You may not have some cheese". "Don't make a mess". "What is this clutter all about?" "Can you clean this up please".
I started noticing intricate maps and plans he had drawn. Then a hanging sign that reads, "The Best Mouse Trap Ever, by J and P"

When I complained that Bella would smell the cheese and eat it and make a mess, he promptly found a bottle of Princess perfume and sprayed as to mask the scent.
When I complained that I don't want to see the mess, he built a retaining wall around the contraption with printer paper.
I finally stopped my robotic cleaning mode and paid attention to what this was all about. J got a DS (handheld game) for Christmas and one of the cartridges was for the classic games: My Simon, Operation and Mousetrap. After playing the digital version of the game Mousetrap, J set out to create his own. Every piece plays a part in his design. Note: the cheese is inside that mini white metal lunch pail. It is propped up with a plastic dome. What you can't see is the sign, hanging above, with a "rope" made out of kleenex tissue and scotch tape holding a magnifying glass dangling above. When J cut the rope, the magnifying glass fell, causing the trap to fall. Genius, no?
I have to share the BEST GAME EVER for creative minds: We got J this Electronic Snap Circuits game for Christmas and he has been buidling projects like crazy. This level builds over 300 different projects. So far, J has built an alarm, a doorbell, a light, a propeller that lifts off and more. Love this.
My kids have been camping:

Santa brought three Expedition Sets, including small tents, sleeping bags, backpacks and accessories. We set up all three in our family room and they have each packed in their Barbies, games, books, headlamps and other treasures like mini homes. See that little pink tent peeking out from inside the blue tent? That is a doll tent, intended for Baby D's babydoll, but Bella Boo has taken over and sleeps inside right next to P. Tent City is packed up today, but will relocate to the front lawn so mama can finally clean.
