A definition of shock

Do you know what it means to be truly shocked? It is when you play “March of the pigs” to your mother just to demonstrate that NIN is not a chillout band and that “Still” is not the only album they’ve recorded (since that has been the only thing you’ve dared to introduce to her so far), and to hear her say afterwards “I loved it! That was awesome!” You’re my mother!; You’re supposed to hate it not to love it! But I should’ve guessed. She absolutely adores trance music; the faster the better :)) And she’s over 60.
