We dont really say goodbye on the phone. Mostly just 'talk to you later', or see you at the lab, or see you when I get home... blah blah blah. Canadians on the other hand... They prefer the 'bye bye' line. Those things just sound silly to me. The french only say 'hello' when they answer the phone, never in normal greetings. Just an odd cultural thing.
Now, those damn british teeth. What is up with that. I love the antiques roadshow, but I cant even watch the original british version, its like watching the dental version of those car accident films for drivers education in high school.
