That was also the day my company changed our policy from "if you want to work from home, talk to your boss to see if that is appropriate" to "if you can work from home, you must work from home".
My boss and most of my co-workers were already working from home since the previous week (my boss had announced he was OK w anyone working from home), and I only went in on the 9th because I had agreed to meet w someone in the office.
Hard to believe that was 20 days ago...
