I attended G's Spring Convocation of Concordia University in 2004. An old Hong Kong businessman, who presumably sponsored the university, burst into tears when he spoke about how he even hadn't been able to complete his elementary school because of the invasion of the Japanese military during the WWII.

It's Okay for him to burst into tears in front of thousands of people. But it's not very fine for him not to restrain his private emotions at all. Nonetheless, it's sorry for us to know he had lost his childhood and formal education to the war.
