Somebody accidentally set off the fire alarm at my agency clients' office building today . . . we dutifully evacuated, and re-entered the building after having been given the all-clear. About 20 mintes later, it started going off again, this time intermittently. Because the few of us who were still there (they have "summer hours" and try to leave early on Fridays) were in a groove, we decided it wasn't worth the hassle of going back outside. However, around 3:45, I'd had all I could take of the ruckus and called it a day.
I've never been so appreciative of the relative quiet of my home.
