Coworker died and there is a new guy at his desk two days later.

Not much to add to the title. Work at a place and a guy that sits near me died in a car accident. The next day they made arrangements for a replacement and to top it off, put the new guy at the desk of the guy who had just died. To make matters worse, the manager accidentally called the new guy by the name of the guy who passed away, I'm sure by sheer habit. I felt so bad and awkward and I know the new guy did as well.
