想走的不会留，

不知道谁写的专栏，几率有多少。

投坛有人讲过例子的，每几个月就得演一次：驱逐，收到钱，撤诉。这时候才可能有想赶走又撤诉。

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.
