Everyone, including easygoing individuals, come-what-may types, is continuously susceptible to the irksome wrongness of other people. The things they say or how they say them, the things they do or fail to do, or when they do it or don't do it, or where, and so on. This is just the price we pay for not being completely alone, not a bad trade-off by any means. A good portion of the mental energy expended on any friendship goes toward seething toleration of your pal's unceasing idiocy (don't worry, he feels the same about you). The deeper the friendship, the worse it is, because better friends get under your skin more easily, their peevishness or fatuous opinions or hair-pulling intransigence will seep into your emotional water table and make you literally sick on a daily basis, but what're you gonna do? You love the big galoot/little snot/overbearing gasbag/shrill harpy/raging bitch/mewling yutz, etc. Their compensating virtues are undeniable, they understand you, they make you laugh, they listen to you moan about your wretched boring life, what more could you want? The tense frottage we engage in with the character flaws of our loved ones keeps us sharp for the real battles, the wider world of life's genuine rectums, sociopaths, and truly unpleasant people we deal with every time we leave the house, especially if we're going to Walmart.
