You're thinking about things that make you... you. That's your box.

[Draws a box in the air.]

You think things feel wrong because they aren't things you've put in your 'box'.

But your box is so rigid and 'tight' that you don't know things that could fit in the box other than what's in it.

So Noriko's trying to help you get outside your box, so you can find new things, and maybe make a bigger, more different box.

...Does that make sense?
