1. You stop giving a shit about garbage.
Sure, you were mortified when you first saw the block-long piles of leaky garbage bags teeming with rats stacked outside of every building in the city at night, but now they are just part of the scenery.
2. You have picked a “totally fine” piece of furniture up off the street for your apartment.
Of course, since that bedbug fiasco, you have become completely adamant that neither you nor your roommates ever do that again.
