As well as the obvious things that hit you immediately when you arrive, such as sights, sounds, smells and tastes, every culture has unspoken rules which affect the way people treat each other. These may be less obvious, but sooner or later you will probably encounter them and once again the effect may be disorientating. For example, there will be differences in the ways people decide what is important, how tasks are allocated and how time is observed. In business and academic life, keeping to a schedule is important. You should always be on time for lectures, classes, and meetings with academic and administrative staff. If you are going to be late for a meeting, do try to give advance notice.
