When my office was in the old Chronicle Building on Sprague Avenue, I frequently had passers-by tap on the window — often school kids lined up and waiting to go on field trips.  That hasn’t happened since I moved to the fourth floor of the S-R building.

Until today.  Maybe the window washer was just being friendly, but I suspect it’s SOP to alert office occupants so they won’t be startled or do something embarrassing. Either way, it got my attention.

What’s getting your attention today?
