I understand the confusion

The most polite way to start a Canadian “fuck you”, using ‘I understand the confusion” can be used to start the most polite “fuck you” statement any person will hear in their entire life.

Me: “What colour do you all see?”
American: “Why did you spell ‘color’ with a u?”
Me: “I am sorry. I understand the confusion, but I live in Canada where we spend things correctly.”
