If you go in the building and design and stuff, and if you're making things...

I remember in primary school, one boy, not me, was arguing with the teacher,

why do we need to calculate the area and things like that?

What's the point of this?

It is the most useful part of life.

Yeah, but the English teacher said you cannot come to the lesson

and if your teacher or so can't see, why not one more time?

It's time, because if you want to deduct more time on English and more math,

you can manage it before that, but I think it's going to be a bit difficult.

And I can't remember, the part of math is like...
