Best Selling Secret

When we were 8, the main characters in the show were our parents' age.
When we were 18, the lead actors were around our aunties' age.
When we were 28, leading roles were our age.
when we are 38, main actors are a decade younger than us. Actors of our age have become parents of teenage children.

At random, my mother found a HK sitcom on our cable called "Best Selling Secret". I was surprised to see Esther Kwan, 44, played a mother role who has a son of about 20 yo in the show. 

Actually, I have begun to enjoy this late 30s phase which friends' teenage children calling me Auntie ;-)
