Andrei gains skills in reading notes, ignoring them

We don't watch TV on Saturday mornings, but every other morning that's the first thing Andrei does when he gets up. Brent usually lets him watch a show or two so he can sleep later. But on Saturday, I'm home so I hang out with him instead.
This Saturday I had to work, so I left a post-it for Andrei that said "NO TV" I was fairly confident that he would be able to either sound it out, or ask Brent what it said.

When I got home I saw that my note was crumpled, but still on the TV, so I knew it had been seen.

What actually happened is this...

Andrei: Look papa, what's this say?
Brent: (still half asleep): I don't know
Andrei: It says - no TV!
Brent: .... Didn't you already watch a movie?
Andrei: yeah...

I'm not sure if I should be proud, or ticked.
