I'm not really a superstitious type but the fact that my parking space is numbered 13 sometimes gives me pause for thought on the morning of one of my course's numerous exams. In England, 13 might have been skipped. Here, things are different:
Fourteen is considered unlucky because it contains the number 4 (which my car park also misses out). One pronunciation of 4 is "shi", which is a homonym for death in Japanese.
