Keys are exchanged

As Oliver was returning the key he noticed that Rico was also holding a key of about the same size. “Is there any chance that I could borrow that key that you have in your hand?” asked Oliver. Rico said that he didn’t think that Bob would mind as long as the key was brought back soon.

They exchanged keys and Rico went to open the box.
