Things didn't happen the way they did in the first two games.

Things have not happened as I was told they would.

Things happen in the present, go away and then something else comes along.

Things can happen one after the other in a few minutes!

I have just tried to do my job and make things happen.

The same thing had happened in front of the house.

Perhaps these things happen by the will of someone from above.

Or put another way, why do bad things happen to good people?

"But I think one can see how such a thing could have happened."

The show was now less than a day out, but many things had happened.
