Ever note, Lucilius,
When love begins to sicken and decay
It useth an enforced ceremony.
There are no tricks in plain and simple faith;
But hollow men, like horses hot at hand,
Make gallant show and promise of their mettle;
But when they should endure the bloody spur,
They fall their crests, and like deceitful jades
Sink in the trial.
— William Shakespeare
