My Calling Cards

Was I just here? There's only one way to know for sure:.. Do you see ____ ?
  1. Stray hairs.
    Long blonde straw-like wavy hairs.
  2. Bobby pins.
    I wish I could get a handle on them, as much as you. It's not like I want to spread them around.
  3. Empty water bottles.
    Like a thief in the night, I will drink all your water.
  4. Empty coffee cups.
    Plural. Caffeine > Oxygen.
  5. My phone.
    Because, yes, I did forget it.
  6. My shoes.
    I probably took them off. I probably left without them.
