An upset monk

In a monastery, a new monk takes a vow of silence. He agrees to the tradition in this particular monastery of saying only two words every ten years. After the first ten years has gone by, the monk is summoned into the abbot's office. The abbot nods, and the monk says "Lousy food." Then he turns and goes back to his room. After twenty years, the scene is repeated, except this time the monk says, "Bed's hard" before he returns to his room. At the thirty year mark, the monk frowns and says "Place stinks" and stomps back to his room. Finally, on his fortieth anniversary in the monastery, the monk storms into the abbot's office and shouted his two words: "I QUIT!" The abbot looks at him and says, "Well, that's no wonder. You've been complaining ever since you got here!"
