The conversation between human and AI assistant.
What was the significance of Severus Snape and Lily Potter having the same Patronus?
That's interesting. Can you tell me more about Patronuses?
Certainly. Patronuses are a type of magical creature that are produced by witches and wizards to ward off dark creatures called Dementors. They are a manifestation of a person's strong positive emotion, such as love, hope, or joy. The Patronus charm is performed by saying "Expecto Patronum" and casting a powerful burst of energy.
