Robert Greene

you have more to fear from friends than from enemies

Be wary of friends—they will betray you more quickly, for they are easily aroused to envy.

You must be the master of your own face. Call it lying if you like; but if you prefer to not play the game and to always be honest and upfront, do not complain when others call you obnoxious and arrogant.

Men are more ready to repay an injury than a benefit, because gratitude is a burden and revenge a pleasure. Tacitus, c. a.d. 55-120

Friends often agree on tilings in order to avoid an argument. They cover up their unpleasant qualities so as to not offend each other. They laugh extra hard at each odier's jokes. Since honesty rarely strengthens friendship, you may never know how a friend truly feels. Friends will say that they love your poetry, adore your music, envy your taste in clothesmaybe they mean it, often they do not.

Strangely enough, it is your act of kindness tiiat unbalances everything.
