Pushing his luck

Bought a box of Paddle Pop from NTUC earlier this evening, but told Aaron that he cannot have them when we get home coz it's late already.

Then, back home, when Nadine's eating her supper ...

A: Mummy, I want supper
M: What do you want?
A: I want .... popsicle
M: No, I said no popsicle for supper right?
A: Oh, I thought that word will not pass ...
M: You mean, you were trying your luck?

How did he learn to think and talk like that???
