The Honeymoon's Over

One of my co-workers is gone on his honeymoon and on the office calendar it says he's out May 15-28. The admin comes into my office and says "That just doesn't make any sense, why would he come back the day before a major holiday?"  So I politely corrected her and told her I believed the 28th is the last day he's off, not when he returns to the office.  She was like "Ohhh, duh that makes sense now."  Guess she was just having a blond moment, although her hair is white, same thing right?
