Are you... French?
At work today a guy came into our office, wanting to know if we had any jobs tutoring French, and we ended up chatting in French (me being the bilingual agent, lol). What I thought was funny is that despite being raised in Paris, he asked me if I was French, or possibly Québécois. I guess I should put more stock in my level of spoken French, but still.
In unrelated news, here's an interesting article about a Canadian-ownded french fries plant in England that had to be evacuated last week when its batch of potatoes from the Continent contained what was thought to be a grendade from the First World War! It's amazing that stuff is still in the fields, over 90 years later, but I saw some of it for myself when I was in northern France.
