Why does amanda say that the silence is golden and the freedom is sweet ?

Dear Student,

Amanda's mother always keeps on nagging her for her mistakes like biting her nails and for not sitting in right posture. Her mother feels that she is very lazy. This continuos nagging makes Amanda feel that her life is not free and peaceful.

​​​​​​Amanda said that the silence is golden and the freedom is sweet as her mother used to give her instructions and that doesn't let her enjoy her freedom. 

Regards
