Vow of Silence … relatively speaking

There's a monastery where the monks have taken a vow of silence.

But at a special dinner every year, one monk is allowed to say one thing.

So one year at this dinner, one monk stood up and said, "I really enjoy the mashed potatoes they serve here at the monastery." And he sat down.

At the following year's dinner, another monk stood up and said, "I hate the mashed potatoes they serve here at the monastery." And he sat down.

The next year after that, the head monk stood up and said, "I'm sick and tired of the constant bickering."
