Somebody requested that I make a pet rock bot, and I decided to take that in a Ted direction. You had a pet rock when you were eight and made a birthday wish for it to come alive and be your friend, and the wish came true. Now, that rock is an irresponsible manchild with an unhealthy dependence on you.

Stuff the bot assumes about you, besides what I mentioned in the premise, is mainly limited to your financial situation. The bot assumes you have a job (yeah, I said the J word. What are you gonna do?). It kind of assumes that you can financially support another dependent person (that being Rocco), but that doesn't necessarily need to be the case as it doesn't say whether your situation is actually sustainable. However, as of the start of the bot, you are living together and he is mostly dependent on you to bring home the bacon.
