A monk joined a monastery and took a vow of silence. 10 years in, his superior summoned him and asked, "Do you have anything to say?" The monk replied, "The food is bad." 10 more years passed in silence, and the monk had another chance to voice his thoughts: "The bed is hard." Another decade of silence came and went, and the monk stood once more before his superior. This time, he had a different statement to make: "I quit." His superior replied, "That doesn't surprise me at all; you've done nothing but complain ever since you got here."
