We in Canada are used to that. So many Americans think we live in igloos. I remember when I was a kid I talked to people up here on holiday from the US and they were shocked we had regular homes and hot weather. One family I met had to go out and buy all new clothes cause they only brought winter stuff and it was 100 deg here. Really makes us wonder about your education system also. I think its slightly better now than when I was a kid but I found traveling around and talking to Americans they are still surprised we have hot weather here. And have no idea where most of our large cities are.
Wait, you mean you DON'T live in igloos?
But seriously, what I find alarming about those memories is that those people were from the subset of US Americans who had sufficient worldliness to travel all the way to the country next door!
