说明

A man in a truck pulled over in front of our house very early yesterday morning, got out, looked around as if worried he was being watched, and then put this bottle of laundry detergent carefully on the ground. The area is basically a vacant strip of land connected to the pond; no one owns it, as far as I know, but it is very close to my house, and it seems unlikely to me that this person was actually just throwing out laundry detergent, given the way he behaved and how he disposed of it. I don't know what's in the bottle but I don't want to dispose of it myself in case it is toxic or dangerous.
