Little snail asked mom: Why since we were born, we have to carry this hard and heavy shell?
Mom: Because our body has no support of bones, can only crawl, and can't crawl fast. So we need the protection of this shell!
Little snail: Caterpillar sister has no bones, and can't crawl fast, why does she not need to carry this hard and heavy shell?
Mom: Because caterpillar sister can turn into a butterfly, and the sky will protect her.
Little snail: But earthworm brother also has no bones and can't crawl fast, and won't turn into a butterfly, why doesn't he carry this hard and heavy shell?
Mom: Because earthworm brother can burrow into the soil; the earth will protect him.
Little snail cried: We are so pitiful, the sky doesn't protect, the earth doesn't protect either.
Snail mom comforted him: "So we have a shell! "We don't rely on the sky, and don't rely on the earth, we rely on ourselves.
