whenever we pass them, my boyfriend and i buy the little critters from the 25-cent machines on the street. animals, jewelry, homies, etc. we put them up on the shelf in my building's staircase (at the second floor) to see how long it takes before someone notices/takes. usually they are gone within a few days. a miley cyrus heart charm stayed on the shelf for an exceptionally long time. three-ish weeks.
the first one we got was a little pig in brooklyn. the very first week that we met. smile.
but, really, who is taking them?
