I know my trash man has been angry at me in the past when I've piled trash high on the sidewalk. It was all bagged or boxed, but he stopped me as I was leaving for work and told me that it was too much for one day. I got out of my car and helped him throw everything into his truck, and since then I've had many conversations with him in my head.
There have been several subsequent occasions in which I've thrown out huge amounts of trash, and I'd like to think that by now my trash man as built a grudging respect for my disposal ability. Sure, he'll sometimes leave a note on large, clumsy objects, but in those notes I detect hints of admiration. Yes, I can disassemble the deck swing so it fits in your truck!
Even when my trash doesn't exceed the capacity of my can I hope that he notices how heavy it is.
