Some people are very bossy and like to tell everyone what to do, but of course they do not wish to soil their hands. You might call that type dic-taters.
Some people never seem to be motivated to participate.
They are content to watch while others do. They are spec-taters. Some people never do anything to help, but they are gifted at finding fault with the way others do things. Some people are always looking for ways to cause problems. They look for others to agree with them.
