We are all familiar with Jesus' admonition to "Do unto others as you would have others do unto you."  Perhaps he could have qualified that a bit with:

• but don't be too specific and

• but don't expect of others that they do unto you as you do unto them.

Considering that the term "do-gooder" is generally used in contempt, just what is the difference between a "do-gooder" and a "good doer?"
