On the subject of truth...

The truth will set you free!  There is no point in lying for any reason.  If you tell a lie you will most probably have to say another lie to cover the one before and you end up being in a vicious cycle with no end.  At some point you will have to go through the embarrassment of revealing the original lie.  So, there is not point in suffering through this negative cycle which is full of stress.  Save yourself some trouble and tell the truth always no matter how painful it seems to be.
