on heaven's door

(tonight i knocked a code into the wall, it was a secret code that nobody knows, maybe not even myself. and then... my neighbor knocked back! i have never seen him except once in the elevator. i don't know the exact words of what he knocked back, but i got the message. i think i mostly just know what kind of person he was by the fact that he knocked back. i like to think i know everything about a person just because i know almost nothing or just maybe one little detail. like how he goes onto his balcony to smoke every night and during the day he plays his guitar and no one else is ever at his home. i wonder if he knows my code. i think he knows my code.)
