When I can't find ignorant to be told,I feel that I am ignorant. Any knowledgeable must relate himself with another ignorant by another ignorant(knowledgeable). And any word spoken need be analysed for sense and name.

Tell and leave that word to other for changing himself by himself.
How can one change other?
Tell at every oppurtunity and leave it.
Telling and leaving is between ignoring and forcing to do.
When you are ignoring to tell,you are ignoring yourself in society.
When you are forcing other to do,you are forcing yourself into slavery.
