Sometimes:

There's a zen saying:

Sometimes it rains on the good people.
Sometimes it rains on the bad people.
And sometimes it just rains.

However an important part is missing, the ending. The missing ending is as follows:

Mainly it rains on the good people because the bad people grab most of the umbrellas in a downpour.

I can't remember where I read that, but I wonder if it's true.
