"At least another sixteen years. But when you're eighteen, you should still be in college," Suansuan explained.
"How long is sixteen years?" Tangtang asked again.
"A long time." Suansuan also couldn't explain how long sixteen years was to Tangtang. He could only give a vague answer.
"How long is a long time?" Tangtang completely treated Suansuan like a treasure trove of questions.
"Let me put it this way! A year has twelve months, a month has thirty days, sometimes thirty-one days. A day has twenty-four hours, and a year has three hundred and sixty-five days," Suansuan answered with a string of numbers.
"How long is twelve months, and how long is thirty days then? And how long is an hour?"
Tangtang's words had Suansuan nearly at the brink of collapse. If he answered, would Tangtang then ask: How long is an hour, how long is a minute?
