Hypocritical friendship is like a shadow; it follows you closely in the sunlight, but leaves you the moment you step into the darkness. — Francis Bacon
New truths often make people uncomfortable, especially those in power; yet, amidst the long history of cruelty and paranoia, they remain the greatest achievements of our wise and cautious humanity.
Use social favors where they matter most: save key friendships for critical moments and do not squander their kindness on trivial matters. If you spend them all on trifles, what will remain for the future? The emotional ties or people who can protect you are far more precious than anything else.
The reason life feels so exhausting is the inability to let go of ego, the reluctance to drop pretenses, and the struggle to release emotional entanglements.
虚伪的友谊有如你的影子；当你在阳光下时，它会紧紧地跟着，但当你一旦走进阴暗处时，它会立刻离开你。——培根
