1. At the ages of five and two, you both really enjoy playing together...with the same thing...at the same time...for a little while.
2. After my first coffee, and about 5 minutes of trial and error, I can actually remember how all of the tracks fit together. Occasionally, I can even figure out how to add a second rail line.
3. I have enough sense to take a picture to remind us all of points 1 and 2.
