TED #3: Derek Sivers: Weird, or just different?

Its interesting to think that something that is completely normal for us in the US can make no sense in some other place in the world. The example Sivers uses is the way we view streets and blocks. In the US we find where we are by looking at street names but in Japan they name blocks instead of streets. These are things that are completely normal and pretty much common knowledge for each culture. This proves that some of the things we take for certainties or obvious facts,may have an opposite reality in some other culture.
