This is an interesting take haha. I’m Canadian and have never once heard of Americans being nicer than Canadians - it is part of our national identity that we’re"oddly nice". I’ve heard more of the “Americans are big and take up space” commentary from above, and have even heard it in Canada (and we share a lot of cultural similarity). Not saying you’re wrong, I just found this such a reversal of my experience I had to comment. Overall, I love my siblings to the south :)
