The guy outside.

It's easy to get distracted during a meeting, but this week it was the worst:
The person speaking had his back to the window. Behind him, outside, the most inexplicable thing was happening. A normal-looking guy was walking through the park, pushing a grocery cart. He left the cart on the path, stepped into a wooded area, and returned with a large trash bag stuffed with "something". He placed it into the cart, wheeled it another 15 feet, and repeated the same thing. He did this until the cart was full, then he turned around and started pushing it down the street back the way he came.
I ask you: what was going on there???
Needless to say, I couldn't pay much attention to the meeting.
