Come not between the dragon and his wrath.

To be in anger is impiety, but who is man that is not angry?

Kindness nobler ever than revenge.

I’ll look to like, if looking liking move; But no more deep will I endart mine eye than your consent gives strength to make it fly.

There is no vice so simple but assumes some mark of virtue on his outward parts.

Love's not Time's fool, though rosy lips and cheeks within his bending sickle's compass come.

Et tu Brute! (You too, Brutus!)
