My aunt has a best friend "Bea" in China. I've met Bea a few times. She is always cheerful, with a big smile. She talks often about how she appreciates her husband of 30+ years for his kind heart and loyalty. Three years ago, I told her during a trip to Beijing how much I wanted to eat candied gourds, because I read about them in books but never ate them. She took me around street vendors until we found a good place that sold them.
Once, Bea told us about how much she loves the fruit market near her house. She said that the vendors all know her and greet her by name (or call her "sister" as is the local custom). They save her favorite fruits for her, off to the side.
My aunt was curious, so she went the next day with Bea. Afterwards she told me, "Those vendors gave her fruit that was over-ripe! Those fruits are going to rot in a couple days. They were basically cheating her, yet she's still so happy."
I felt sympathy that Bea was being scammed and didn't even know it. I thought my aunt is so much more sensible for catching on to the fruit vendors' tricks. But now I think Bea is the wisest one of us all. She is happy-go-lucky and carefree, eating her overripe fruits, surrounded by a legion of friends because she is so fun to be around. She has one of the best marriages I've seen. Her daughter and son-in-law get along perfectly with her, and visit her frequently. She is over 60 but looks at least 10 years younger.
Bea gave me a hand fan once, which said in calligraphy, "Cherish being oblivious".

As she gave it to me, she said that if you calculate every penny and argue every grievance, life is exhausting. Instead, let yourself be oblivious sometimes. "Yield a step," she said, "Give an inch. And you will see that life is as limitless as the ocean and the sky."
