"Why'd you do it?"
Snowflakes fall upon K as he reaches his expiration. All this time believing he was special, but the truth strips that away. This desire of wanting to be special is something we all have; for some cases, it may be true, but in a world where the fiber of almost everyone living is replicated, someone special is hard to find. But I like to think that K is happy as he expires. He may not be unique, but he dies doing the most human thing he can.
