Is this maybe about the cycle of drugs and rehab? Getting clean and then regressing? It sounds like part of it takes place on a doctor's exam table (there I was, laid out on a table... bare feet to the floor)??? maybe lying to yourself that its gonna be okay this time (behind the smile, a tongue that's slippin) or maybe something of the music industry? (here i sit writing on the paper... sign the deal) probably a stupid interp... any thoughts?
