With these hands...

Don't know what went on in our small dog walking park last night. Usually there is no litter but this morning there was a quite a bit. The ubiquitous can of Fosters was joined by two milk cartons and two bottles of water, all appeared empty. Then on the other side of the park looking forlorn and lonely, this pair of latex gloves.

I can't imagine what was going on to generate such rubbish, any suggestions?
