哥哥 the Engineer

Last Friday, after fetching 哥哥 from school, we went to the 24 hours coffeeshop for lunch. As it was raining heavily, we decided to loiter around while waiting for the rain to stop.

As usual, 哥哥 stopped at the escalator, which has a glass panel so you can actually see the parts moving. He then started explaining to an auntie who was nearby, how the escalator works. The auntie was so nice to squat beside him listening to his 'lecture' for close to 20 minutes. When she asked him how he knows all these stuff. He said, I know! I see and learn myself!
