I like sarcasm as much as the next....what?

I traded emails today with a "person" I work with.  He sent me an email with questions about three or four projects.  I summarized the status of the work, covering his query.  He though chose to send the following email: 

 "Mike-  Please reply to my questions - they are the ones with question marks.  It would be very helpful."

Speaking of bad mood swings!

Yes, I had a myriad of responses but I did not go there.
