2. [ ] and enjoy talking with people with a sense of humour. Jokes are usually welcome.
3. [ ] a small wet cloth at most Japanese restaurants. Use this to wash your hands before eating, then carefully fold it and set it aside on the table. Do not use it as a napkin, or touch any part of your face.

5. [ ]. So be careful — they will assume that the first of you walking in the room is the head of the delegation!
