I’m American, and happened to be on a tourist bus in London. Sitting to my right were a group of Quebecois. To my left a pair of Newfies. I talked to both groups independently over the course of the trip. Both groups were incredibly friendly and engaging to talk to! However, both groups were staring daggers at each other whenever they’d look in each other’s direction. Each group of the Canadians were not particularly polite to each other.
