person A: Sometimes I'm just surprised and amazed at the kindness of others. Recently_comma_ one of the maintenance men in our complex delivered a package to me_comma_ without my saying anything!
person B: Wow!  What was in the package?
person A: It was a carpet/upholstery cleaner and is quite heavy. I'm disabled_comma_ so wouldn't have been able to carry it. They don't normally do deliveries_comma_ so I thought that was really nice of him to do that.
person B: That was really nice!  What a wonderful surprise!  This act of kindness helps to restore my faith in humanity.
person A: The service they provide is so considerate and thoughtful. I'd probably move out of the complex if it wasn't for the staff!
