One of my coworkers had an odd reaction (to me) - he also sits by the window, and I asked him if he had been able to make out who they were from what they were saying. "People without jobs, trying to tell us how we should take care of them!" was the beginning of his acerbic response, which went on until he noticed my blank look and paused, took a breath and admitted no, he didn't know who they were. Um, ok... I hate it when I step in somebody's issues like that.
Now, judging by the novelty horns, we are being assailed by Seafair Pirates. When I'm in a good mood, they always remind me of the Monty Python sketch at the opening of one of their movies with the bankers turned pirates sailing off in their building.
