There was nothing like getting stuck in a car for a LONG time while some nincompoop was yapping away at a door totally heedless of anybody or anything else. This happened to me a couple of times. Once it was because the brother was just absent minded, the other times it was because the brother was just plain inconsiderate. One smart aleck said that I should have gotten out of the car and knocked on some doors in the meantime!!
It was my opinion that people like this should work alone if they refuse to adhere to any kind of schedule.
