Today we had an occurrence that was new on me. I was at my desk at work at about 5 minutes before 2pm when there was suddenly a general announcement that Zimmer building 5 would be closed at 2 o'clock and would not be reopened until the evening, and everyone should leave and take your belongings with you immediately. Nobody knew exactly what "closed" meant but everyone left and didn't come back, except me, because I had a 2:00 meeting in another building that was not "closed." The meeting, of course, was supposed to last a half-hour but lasted an hour and a half. So my free few hours off was cut short. Anyway, as we learned during that meeting, the reason for the abrupt closure was a bomb threat. WTH? Apparently there are disgruntled workers at Zimmer.
