We ate at Changi Village and on our way back to the car, we saw the
bumboats at the terminal.

G: Mummy, bumboats bump in the water.
M: Oh... Why?
G: Because they are called bumboats. And they can bump only once in
the water.
M: ??? Why?
G: If too many times, the people inside will all fall into the water.
And the driver will wonder where the people went.
M: Hahaha

Last week when we went by VJC, Fred pointed out to him that that was
his old school.
G: No Daddy, that's not your school.
F: It was.
G: No it's not! You are too big to go to school!! Schools are for
children only.
F: ???
