Since we're talking about language again, here's something I've observed lately. I've noticed the UK boardies say, "maths." I've never heard that before. It's just math in the US. I'm taking science, English, and math. Interesting. Also, I've seen "vacations" a lot, too. We'd only say that if were you taking more than one vacation. Every day I learn something new from this board.
Same language, different words. It happens the same in Spanish. Sometimes I use words that Southamerican boardies don't understand or vice versa. I think it's really funny :D
