I was catching the London underground this evening with two Chinese friends, heading out to dinner - we were speaking a mix of English & Chinese. Sarah & Jessica were telling a funny story about a time soon after they arrived in London, when they were gossiping in Chinese about someone on the train.
To their embarrassment, that person actually could speak Chinese!
And the funniest thing happened tonight. While they were telling the story to me, a Westerner turned to us and spoke in really good Chinese, "Can you speak a little louder, I can't hear everything you say."
Turns out he lives near me, and is married to a Chinese woman from Yunnan Province.
It really is a small world!
