If we have to go out on business tomorrow, and it happens to rain heavily tomorrow, we can change our mind and not go out for the time being. Let's do some indoor things at home first and then go out another day. If that thing is very important and we have to do it, then in the face of emergencies, the problem of rain can be ignored. The fate of "unexpected events" is greater than the fate of the weather, so we have to follow the big fate.
