I hadn't seen them in a while and wondered if they'd reappear. I kind of thought they would, since they usually do.
Sure enough, I spotted them on my way to the train station this morning. I don't like them very much, but I have to admit they're usually very industrious. I guess there's a lesson to be learned from them. They seem to usually have a system going and get things done.
Here they are, up above, shown on one of the sidewalks, going about their business. Can you tell what they are? Have you seen any lately? Do you have any stories about them to share?
