What if fortune tellers always stop my mother?

Does your father believe it, too? So you have no materialism at all? First convince your dad that these things are not credible, and your mother doesn't have to care too much. They have been married for decades. Don't you have this tacit understanding? Let them believe that at least this has not happened now, and no one can foresee what will happen in the future. It is better to live a good life and be sincere than to look on coldly all day!
