Have you come to help your old Dad, my boy?

He had been getting to like old Dad pretty well.

He's really let himself go since my old Dad died.

She still comes to see her old dad, my little girl.

My old dad saw them once when he was a boy.

But we never saw him with anyone except his old dad.

Could be she's right there at your side looking down on her old dad.

"Dad just old me about the marriage and I had to come meet you."

Going to give good old dad the surprise of his life when I get home.

Apparently this is what has happened to the old dad.
