Imprisonment!!

A mother writes a letter to her sun, who is in a prison. - Dear sun, life's so hard for me since they took you to a prison: nobody digs a vegetable garden, nobody plants potatos... The sun writes back to her mother: - Mom, please stay away from the garden. If you start digging it, the police may come and both take you to a prison and prolong mine imprisonment.. Mother writes back to her sun: - Darling, together with your last letter police came. They digged all over the garden, but haven't found anything. The left being extremely frustrated. Sun writes his mom: - I helped as much, as I could with this. Please plant the potatos by yourself.
