We had an uninvited guest in our living room recently. A dragonfly had somehow wandered into our house, resting itself on the metal rope dangling down from our ceiling fan/lights.
Cheng Kai was truly "hyper-excited" - wanted me to catch the dragonfly, or perhaps tied some string around its tail, as I had done it in my early childhood days.
I once told him that I used to catch dragonflies in the open field opposite my parents' house during primary school days. I would hold it by its wings, and then tie a string around its tail. The dragonfly would then be "let loose", with the string hooked around my index finger. It felt like I was flying a kite!
Then, CK asked me a question: "What did I do to the string that was tied to the dragonfly eventually?" I was stumped momentarily. I didn't think I had untied the string and removed it from the dragonfly at the end of the day. The poor dragonfly probably flew off with it! Come to think of it, it was quite a saddistic thing to do then! Well, it was 40 years ago....
