I believe that we come into this world with an empty tablet.  Then, as we grow, people write on our tablets.  People write things of love and kindness, or sometimes pain and destruction.  Some things are written on our tablets in pencil and are easy to erase.  Others are written in what seems to be permanent marker, and takes more effort to remove. 

My tablet had worthlessness in a 76-pt. font, of permanent marker.
