  Sienna: What did it look like?
  Greg: Well it was black color Acer laptop.
  Sienna: I guess John was carrying an Acer laptop in his bag.
  Greg: yep i remembered. I left it at the cafe while having a cup of coffee with John and he might have picked it up.
  Sienna: Yeah, he might have.
  Greg: Thank you Sienna
  Sienna: No problem
target: Greg left his black Acer laptop at the cafe today. John was seen with it by Sienna so he probably picked it up.
