For some reason, the new favorite activity in the office is throwing paper airplanes out of our 26th-floor windows. Then, everybody crowds around the open window and roots for the paper airplane. They cheer them on as they loop away, and shout happily when they miss running into adjoining buildings. And then they all go "awwwwww" when they lose sight of it, or it crashes into the ground, or a passing bird, perhaps.
I have yet to join the ranks of airplane-tossers, (I never was the type to crowd round when there was a fight in middle school -- I do not think I will crowd round for an airplane either) but this does give some indication as to the level of activity 'round these parts.
