Are kids in CAIS happy

Heard a lot here that CAIS is a caring school. But from my observation during the school visit at Lai Yiu, the children there are so quiet and bit less of energy. They were not keen on responding even the principal talk to them.

Would parents advise whether your child is happy at school? Do they love their school? What's the style of teaching? Encouraging children to explore by their own or spoon feeding them knowledge? Is your child enthusiastic in learning?

Thank you very much!
