Why do children love and admire garbage men so much?

Children are very innocent and they are easily drawn to the idea of helping their parents with daily chores and someone who is doing great in their community. Seeing a Garbage person each week picking up our trash riding the truck gives them ideas in their little minds that this is great and exciting. Like they see it in a daily basis their curiosity arises to check on them daily so they are more drawn to the person and what they do. This was pretty exciting to the ones leading a mundane life. They were friendly too.
