Waking the dead

My sister tweeted this today:

I've had my license for 20 years and I always thought that the larger vehicle always had the right of way. Apparently that's only true at sea.

This is not surprising. 

I took my sister out for her first driving lesson when she was sixteen.  We drove around the cemetery where our mother is buried today, the same cemetery where I learned to drive two years earlier.

Fifteen minutes into the lesson, she drove up an embankment and knocked over a headstone. 

I never took her for another lesson, and have not tried to teach another person to drive since.
