Maybe because Su’u school sits on top of a mountain. I have a friend from Nepal. Nepal is a tiny country between China (or the Chinese province of Tibet) and India. Nepal is a mountainous country. In fact, the highest mountain in the world, Mt Everest is in Nepal. My Nepalese friend is an avid mountain climber in his younger days.
He was telling me about the most satisfying and most frustrating aspects of mountain climbing. The best part of mountain climbing is when you finally reach the top of the mountain. It is a very satisfying feeling. You reach the top and celebrate, congratulate your colleagues, punch the air, shout and laugh.
