While waiting for the bus, I chatted with Calder on WhatsApp again and found out he didn't quite understand the concept of male vs female. After the chat, I got him to search for familiar singers (Peggy Hsu, Norah Jones, Sarah Brightman, Jay Chou) on Google images and checked if he could tell between male and female, man vs woman. He got it right by then. Next step: install a Google widget on his hp.
(In today's chat, I also guided Calder to use "I see" to end a conversation.)
