Erdedy waits for the pot delivery (p. 20)
He'd had to buy a new bong at Bogart's in Porter Square, Cambridge because whenever he finished the last of the substances on hand he always threw out all his bongs and pipes, screens and tubes and rolling papers and roach clips, lighters and Visine and Pepto-Bismol and cookies and frosting, to eliminate all future temptation.
