This is the rule, and there is no way to free oneself of it: as soon as the thought has arisen, it must be followed to the very end.
“This heart that flutters near my heart
My hope and all my riches is,
Unhappy when we draw apart
And happy between kiss and kiss:
My hope and all my riches — – yes! —
And all my happiness.
For there, as in some mossy nest
The wrens will divers treasures keep,
I laid those treasures I possessed
Ere that mine eyes had learned to weep.
Shall we not be as wise as they
Though love live but a day?”
James Joyce | Chamber Music
