interrupted work

As I sat in watched in fascination as the bees moved about, a branch fell off the large tree that shaded the spot where they worked. The sudden movement as the falling branch hit the dead wood shook most of the bees loose. I thought they'd get angry and head in my direction, but these were bees on a mission! They swarmed around the general area and then headed right back to the unfinished honeycombs. The Queen must be a slave driver!
