Slip of the tongue

As I was preparing my list of reservations, I realized a different coworker was coming in later and got excited. A coworker's wife had a baby boy so he took a week off. The next minute, the bossman calls over and we go through the usual, How are you?, riff. I replied that I was enjoying my (coworker's name) free weekend. He replied with an unemotional, Well that's good. Later I thought, maybe I should not said that. I am unsure if the bossman is aware that everybody hates this coworker. He knows now I don't like this guy. Post later. Bye!
