It’s Thanksgiving dinner and magnificent feast is presented before you. It is a time of celebration and happiness, but you want to mark it with solemnity so you bow your head, so you do not speak to your companions. The food is good, but you prefer to think about how you don’t deserve it and what suffering the cook must have undergone to prepare it. Someone calls for a song and you suggest a sad one, something that will inspire guilt in everyone. And the end of the meal you drag yourself up to the host and apologize for causing such pains.
The next week the host invites you back again. Another huge feast, and you wonder why he keeps torturing himself like this.
