When the person who lived in your apartment before you moved in keeps the key then comes back shortly after you move
in and steals small items
of seemingly little consequence
such as a pair of socks, camera memory card, package of hotdogs, or a pocket
knife when plenty
of things of much
greater value are lying around. They may also leave
a telltale sign that something is amiss such as leaving the light switch on, but turning the lamp off.
Aaron: Hey, Emily, were you in my room at all today?
Emily: Nope, why?
Aaron: Cuz someone turned off my lamp, but not the light and my camera memory cards
Emily: Darn previous tenant mischief
