Carpool mixup.

When living and working in a small Canadian bush community in the 1960's my husband was a member of a car pool along with a Harold, a Jim and a Roy. One morning when Harold was due to drive, his wife took a phone call from a Jim to say he was driving that day as he was unable to do his stint during the week. Harold put his car away and the three men, my husband, Harold and Roy stood waiting for Jim at the crossroads. Jim did not turn up so they walked to his house in case there was a problem. Jim was waiting and annoyed that they were on foot and he had been waitingso long. They decided that someone had set them up. Later, however, my husband went through the small local phone book to look for another possible Harold with a similar number. He found one with only one digit difference. On phoning the number he discovered that this other Harold had also been involved in a mixup that day -- when one of his car pool, another Jim, had arrived in his car causing confusion and making that group also late.
