One of our next-door neighbor boys, Ryan, got a new dirt bike two or three months back; just as he was getting really good at riding it, the thing got a flat tire. So for two weeks, it's been parked.
Ryan was in the shop visiting with Cliff and mentioned his bike being down. Cliff said, "Bring it over and we'll fix the flat; it doesn't take a rocket scientist."
When I saw what was going on, I got nervous. Cliff isn't supposed to lift over five pounds, and I couldn't see him being able to keep his hands off this project.
So, with me hovering nearby and occasionally shouting, "Don't you LIFT that!!!", he proceeded to give Ryan step-by-step instructions.
Things went well until it came time to put the repaired tube back in the tire. Somewhere in the process of doing that, the tube got pinched with the screwdriver Ryan was using. All that work for nothing.
At least it kept Cliff's mind busy for a couple of hours.
