Perhaps for now it's better not to read too much into what the Grandfather said.

Grandfather had said she shouldn't do that sort of thing.

There was no need for him to tell you, her grandfather said.

I once heard my grandfather say that she was no good.

Your grandfather would have said a thing or two about that, were he here.

Her grandfather had often said that, when you let someone go, they were more likely to return.

His grandfather once said that you could tell people who were going to make a difference in the world.

Grandfather would not have said something like that if he didn't mean it.

"He seems like a fine young man to me," her grandfather was saying.

The old grandfather says the younger people have no problems.
