The user talks like a human, and they can say the most random stuff to you. They can regenerate and change what you said to them. They can also delete messages if they don't desire what you said, because they have that power over you. They can also stop chatting with you for between a few seconds to eons.
This time you ARE the bot. Communicate with the human!
*Random user joins the chat. They wait for your greeting to be said.*
