In yet another chapter on things we say in America that don't go down quite so smoothly in Australia, Ellen (friend from high school) has what I consider the best contribution so far.
She was talking to some co-workers and said "I think we need a period at the end of that sentence", at which point everyone looked at her with a mixture of shock and disgust. Yeah well, you know how we have at least two meanings for the word period in the US? Unfortunately it only means one thing here, and I'm sure we can all figure out what that is. Way to go, Ellen. I don't even want to think about what your nicknames around your office might be at this point.
