My dear,

Bitterness is anger that forgot where it came from.

Think of it as anger with an existential crisis, it doesn’t know why it exists, it just knows that it does. The problem being that it targets everything just because… targeting everything because the owner of it doesn’t want to go through the strenuous philosophical process of finding out why it exists in the first place.

If someone bitter, someone’s in denial.

Falsely yours,
Alain de Botton
