Did I Miss Something?

Yesterday in the mail I received an ominous blue postcard/letter from my doctor's office. Inside was written the following: "We are pleased to announce that your lab work and tests were all normal." Um, what? Pleased to announce? Am I getting married to my lab results? Why would they word it like that? If it'd been bad news, would they have said, "We regret to inform you that you have two weeks to live?" Plus, they'd already called me and relayed the good news (which gave me a bit of a heart attack, since usually you just get the card, not a call. I'm fairly certain the call = bad news). I don't know. Maybe I missed the memo that my lab results proposed to me and my office is throwing us a lavish party?
