At least he policed his own mess. That's pretty unusual in today's world of no responsibility.
I routinely retrieve neighbors garbage cans when they end up in the street and did the same up and down the street when I walked the dog in the morning. Our street is just barely two cars wide so it just seems to be the right thing to do, at least to me. Some of our neighbors leave for work at zero dark thirty, in the summer time let alone the winter time, so their garbage cans would be in the street all day.
