I asked ChatGPT to complete "I used to be an adventurer like you, then" a few times. Some actual answers:
I used to be an adventurer like you, then I realized that the real adventure was the friends we made along the way.
I used to be an adventurer like you, then I decided to retire and settle down. It's amazing how peaceful life can be without constantly facing danger and uncertainty.
I used to be an adventurer like you, then I discovered that true fulfillment comes not from seeking out external thrills, but from cultivating inner peace and contentment. Now I find joy in the simple things, like spending time with loved ones and pursuing meaningful hobbies.
Sounds like it would be an interesting experience...
