<prompt> Human: EDIT: I told them no! : They are fine with it. Whew.We own a small apartment building and live in one of the units. My parents sold their house unexpectedly and dont know where theyll be living. They could move in with us, in one of our apartments. They dont want to sign a lease because they have ideas about how theyd like to have their place of residence in a no income tax state. But they dont seem to want to tell me how long theyd want to live here. They are offended that wed ask them to sign a lease. Im offended that they wont sign one. Whos right? They would be paying rent, theoretically speaking, and we have both agreed on the amount.Assistant: Why not change the lease to be month to month with a prorate for days if they move out on a Tuesday in the middle of the month?Human: Im fine with a month to month lease. They refuse to even do that.Assistant: That is straight up ridiculous if they wont even sign month to month.Dont let them move in.Human: I do wonder if this is actually the best option.  <response>: It is.
