It is absurd to ape our betters.
If you wish me well, do not stand pitying me, but lend me some succour as fast as you can; for pity is but cold comfort when one is up to the chin in water, and within a hair's breadth of starving or drowning.
Once a wolf, always a wolf.
The quarrels of friends are the opportunities of foes.
Wise men say nothing in dangerous times
The grateful heart will always find opportunities to show its gratitude.
