A GIGGLE BOX, A LEAKY FAUCET, AND A FOGHORN

Every day after lunch Mrs. Jewls read a story to the class.

Dana hated stories.

The last book Mrs. Jewls had read was a story about a pig and spider. The pig was really cute and the spider was very wise.

Dana thought it was a horrible book. It made her laugh too much. Everyone else laughed too, but the problem was that Dana always kept laughing long after everyone else in the class had stopped. It was very embarrassing . And sometimes she broke out laughing at a part that wasn't even funny because she remembered something funny that had happened earlier.
