Work Story (involving Canadian and American spelling!)

So as I was sitting on a milk crate today at about 6:45AM, waiting for the opening of the cafe at 7AM, I was munching on some toast with Peanut Butter on it as I had finished getting ready for customers so I was taking some time to wake up and have breakfast. I was staring at two buckets that are filled with substances that we use for baking. One of them is sugar and I'll leave the other's name untitled. As I stared at the names, I was doing the usual thing with my mind where I look for any similarities between the words. Yes, I'm weird, but this is where I had a revelation!

I have many relatives in the US of A and for some reason, I get teased about "how crazy you Canadians are" for putting a "u" in words such as (in the American form), "color," "neighbor," "harbor," and "labor." Personally, I find the spelling of "labor" to just look back, while I do prefer the look visually of the spelling of "color" and "harbor," but with "neighbor," I just think it looks dumb. So now that I have established that context, here is my revelation. When my American relatives criticise me for putting a "u" in those words, they really are full of it. Here is why: There is a white baking ingredient that all Americans consume (so long as they are not gluten-intolerant). Have you guessed what it is yet? If you have, how is it spelt? It certainly is NOT spelt "flor." What is a "flor?" I don't know, but I do know that it is spelt "flour" in Canada AND America! HA! Take that you self-righteous, American relatives!

PS. I still love you guys....
