When you were six you tried to modify the car. Claimed that with a few tweaks you could make it fly and traffic jams would be a thing of the past. Mum and Dad didn’t take this as a valid excuse and since they couldn’t bill a six year-old for major repairs you got grounded for three months.
Even with an engineering degree Dad would rather call a mechanic than allow you to help, he wanted it fixed, not given wings!
I did try and tell him that wasn’t the design, but it would have helped if I hadn’t been the only one you allowed to see your work.
