Did somebody explained you some-when that every post to this forum must have a question ?


Or you need a special explanation ?



It seems &nbsp;<U>SO &nbsp;STRANGE &nbsp;TO &nbsp;ME</U>,  &nbsp;because it is &nbsp;TOTALLY &nbsp;OBVIOUS.



By the way, &nbsp;simple courtesy just assumes/requires that an educated person &nbsp;<U>MUST &nbsp;ASK &nbsp;A &nbsp;QUESTION</U>, &nbsp;when he comes for help.



Isn't it is so ?



Are you an educated person ?



Did your parents, &nbsp;or other relatives, &nbsp;or in the school teach you about it ?



The routine rule of the life is:


<pre>
    When you communicate with people in a polite, courtesy way, you make friends.

    Otherwise, you create enemies.
