This is a little OT, but I thought I'd share a story.
We were in line at Blizzard Beach and a family behind us heard my husband talking to my son about getting back to the hockey tournament. They immediately came up and asked if we were Canadians and we said yes. We talked to them about hockey like we were best friends. There were no awkwardness. They knew everything about hockey and the man actually played hockey as well and his son will be soon. Mind you, they said they were from New York, and hockey is popular there.
I have had some experience where we were asked if we were from Canada a few times on the resort bus or boat. We were surprised because we didn't wear anything Canadian. But we have been told that we were very polite and that's how they knew.
This happened a few times in the restaurants when my children would order with please and thank you's. We had a waitress say to my son, "you are so sweet and polite, I bet you are from Canada.." my son was in awe. He asked me, "how did she know?". To which, I said, "no clue".

Took me a week to recover from that encounter...

) but it was still warm enough for shorts in the sun. Well I was talking to a lady who worked there she couldn't believe that I had shorts on and said where are you from I said Canada. She was from Mexico so I guess for her it was cooler there. She said she had on long underwear under her uniform a big heavy coat and 2 pairs of gloves. She then proceed to ask me how we got around up there did we have car/vehicals that hover over the snow. I tried so hard not to
and told her no we have regular cars just like you. It only snows in the winter we actually get just as hot as you guys in the summer. She was floored and couldn't believe it. So it's not just Americans that have these typical reactions.
