For a long time, one of Thing1's favorite activities has been taking apart Hotwheels. He periodically asks for a Phillip's-head so he can take something apart. I usually say no and remind him that the toys never get put back together. Instead, I keep the pieces corralled in a cup for a couple weeks and clean around it, then I finally throw the whole business away when I get tired of the clutter. It's not like we have a shortage of Hotwheels. Plus, the cost of a Hotwheels car is less than what my time putting it back together is worth.
Look at the admiration in Thing2's eyes. Later he said, "[Thing1] is a hero!"
Back to business. It was almost together, but I was still not convinced he would see it through. He has gotten to this stage before. Using tiny screws to put it together is the hard part. "Righty tighty. Which way is right?"
This may sound trivial to others, but to a mother of boys who want to be just like their mechanic daddy, this is not a lazy day; it is a pivotal day. This is the day we put away a whole Hotwheels vehicle after he asked for a Phillips-head to take it apart.
