A Cold Snap

'You're pushing walls instead of the door.'

Why is it a complete stranger is able to tell him something more useful than his own big brother who's supposed to be an endless fountain of useful knowledge?

It's unfair but it's also the truth. Walls, and doors. I keep his door locked and maybe I'm not literally pushing at walls but I figuratively am.

I'm still not sure about Kanbara Shinya, though.

He pushed and pushed and pushed and wound up pushed. Is he the window, then? That breaks when it's pushed the wrong way but closes the right?

Then who's the door? The bullies… or his brother?
