Two, both asked on extremely short dates.
1. “Are blind people allowed to use handicapped parking spaces?”
2. (Driving down I-5 north of Del Mar about 8 pm) “Why are the lights on that side” indicating the opposite lane headlights “always white, and these ones” indicating the taillights in the lanes before us “always red?”
Like pup, both were followed by my awkward, unreciprocated laugh, and a horrible dawning realization.
