  Eric: Surely not, just look for it carefully
  Julia: you always "loose" things and find them 3 days later somewhere at home
  Eric: hahaha, exactly, I've heard it so many times already
  Sam: but I haven't been home even
  Eric: so where did it happen?
  Sam: in the city
  Eric: ask in all the shops/offices you've been today, people mostly keep an eye on this kind of stuff
  Sam: right, I will, I'm just a bit panicked 
target: Sam lost his car keys in the city.
