We use a lot of profanity. I won't list that here, haha. I think one of the more strange things that we do is we use a singular "they." (My Latino friends think this is weird) For example, If your friend was talking about their boss at work, and they said: "My boss wants to meet with me tomorrow." If you do not not if the boss is a man or a woman, you might say: "What do you think that they want?" So here, "they" only refers to one person (the boss), but instead of using he or she, you use "they." We do this often, but we don't usually think about it.

I meant to write "If you do not KNOW..."
