For a Canadian, “eh?”is a badge of honour.
We aren't careless of our neighbours' support and value feedback. We often make eye contact too, right? Try walking down a street in Paris, looking for eye contact and experience being invisible. “Eh” shows we look for agreement and have an open sense of community. Canadians even make eye contact with police officers. Try that in Mexico and elsewhere and you’ll find yourself in trouble. Canada’s great, eh?
