What does it mean when...

...you're having a conversation with your boss, and it goes like this...

[Boss] I'm tired.
[Me] I am too.
[Boss] I only have one thing to do today so I'm holding off...
[Me] Read a magazine!
[Boss] I think that'll just make me more tired. I'm going to lunch in a half hour, I'll just research wedding floral arrangements to pass the time.
