"If you don't want to, that's your choice. But... Some believe that there is a god who operates through the pools. People who are kind, moral, loyal, honest, and so on, tend to get more wishes. Violent or disloyal or unstable people get fewer and are sometimes hurt if they ask for more wishes beyond their first set. I have literally never heard of someone being harmed the very first time they touch the pool. Cohabitors are strange to me, but the idea of the pool hurting someone on their first go is much stranger. I have a strong expectation that even if it behaves oddly, it will not hurt you. But again, it's always your choice and I'll shut up about it now unless you have questions."
