Got a example of a new freindship starting out on the wrong foot?

When the wife and I were living in Alberta we met a couple that were from the city we were born in. During the evenings conversation my wife mentioned that her father built the Sydney Opera House and he is now President of carpenters union in Windsor. The guy said BS his father is the President of the carpenters union in Windsor. After 5 minutes of heated arguing it turned out that they were both right - his father was president of the finishing carpenters union in Windsor and my wife's father was the president of the framing carpenters union in Windsor. Cheers!
