school of hard knocks

that's a big wall you got there. mind if I try and walk through it?
not at all, you think you can do it.
it's only a bunch of atoms. mostly empty space. same as you and me, know what I mean?
it's a stone wall. it's going to hurt.
you have any physical evidence of that?
did once. but I learned that lesson early.
the hard way, I take it?
unfortunately.
