Funny story from Florida trip (better told in Chinese, but I type like a turtle crawls): There once was a brilliant astronomer. He knew every star in the sky. He liked to take daily evening strolls to gaze upon the sky, and would often plead with his beautiful young daughter to join him. But she was just not interested. Little girl grows up and heads off to college, and one November day, father receives a letter from his little girl. "Dear Papi, Early this evening on my way home with just an ordinary friend, I finally gazed up and saw Orion and the Big Dipper! What a beautiful sight...could you please tell me what's the names of each star?" To which the father replies "Dear Daughter, I went for a stroll with your mother this early evening too, and though I could see Orion, the Big Dipper doesn't appear in the night sky until around 2 am. Thus, I am very curious to know who this "ordinary friend" is!" Somehow it's a lot more funny when told in C
