Ruthermoor Brurford found himself in a serious bind. If no one ever came to truly know him as his deep, innermost self, he would by definition die alone. But he truly believed that his essential self ran a high risk of being so unbearable as to repulse anyone who put in the effort to really comprehend it. So by demanding the effort of another and putting forth the corresponding effort of his own, he would ensure the fact of his dying alone in addition to sparking no small resentment in the hypothetical other party.
After years of paralytic rumination, Ruthermoor decided to buy a houseplant. After hearing weeks of the intimate details of the workings of his mind, the little shrub opted to shrivel up and die, confirming the worst of Ruthermoor's suspicions.
