David, I love those questions. Thanks for posting them.
Driving the wrong direction - Our local Target store is entered from the street by driving up a steep ramp that leads in a straight line up to the fourth floor of the parking garage. There is a similar exit ramp that starts from the third floor and goes straight down to street level, and opens next to that previously-mentioned entrance. Well, last year, I unintentionally drove UP the DOWN ramp and got nearly halfway up, unawares, when a car started down toward me. Oh Geez! I had to back down. MiniMeno reminds me of this experience nearly every time we go there, even though it was at least a quarter of her life ago.
