How much is too much?

[lizzybennet]

We've discovered that there is a vendor at the Univ. front gate who sells cotton candy for only 2 yuan (equal to about 25 cents). It has been less than two weeks since we've learned about this heavenly treat and we've already had cotton candy three times. I suppose we shall soon discover the long pondered question: how much cotton candy can one eat before it's not a special treat anymore?
