想走的不會留，

不知道誰寫的專欄，幾率有多少。

投壇有人講過例子的，每幾個月就得演一次：驅逐，收到錢，撤訴。這時候才可能有想趕走又撤訴。

Consider this situation, when two sides are fighting, one side is suing in court and the other side just want to pay and make some headache to the landlord. How likely that will happen?

If they want to leave, they will just run without paying anything. Why bother pay some later? Just to avoid late fee? ...

Hence, the conclusion is this event is not going to happen very often. You then have to slect the extra burden to handle checks, accounting etc.

Life is an art of banalancing.
