My husband enjoys tinkering on his motorcycle. Nearly every evening you can find him in the garage taking something apart and working on it. This evening, my five-year-old son decided to do a little tinkering himself. He pulled out his bicycle, a few screwdrivers, and sat down to work on his bike. A little while later, he had taken his training wheels off. He was so proud of himself. Unfortunately he wasn't as good at putting the wheels back on. Guess who had to do that!
