The Little Prince

What are thorns for?
Once he asked a question, Little Prince wouldn't stop repeating it.
- The thorns are for nothing, the flowers show only their badness!
- Oh!
After he said nothing, he said to me as if he were offended:
I don't believe you, the flowers are weak, they're just warm, and they do what they can to protect themselves, they think they're scary with their thorns.
