Trite, right and bright spots of Rio 2016

I thought the Olympic Games, no matter their venue, are meant to be sellout events. On second thought, triggered by Rio's half-empty stands, I think the world has changed.

Sunday's swimming and gymnastics had an unprecedented dimension. Competitors, especially women, from different countries supported, encouraged, hugged or consoled each other, including their rivals. Truly Olympic in spirit as well as looks.

Sunday was Friendship Day, so the Olympians, including Chinese participants, may have decided to showcase love, camaraderie and compassion, against the global backdrop of terror-related mayhem that preceded Rio.
