You are a woman who knows a thing or two, as I said.

I never knew a thing about her husband then, mind you.

Not me, I didn't even know a thing about him until two days ago.

Now, I know a thing or two about health care.

In seven or eight minutes you won't know a thing.

But I know a thing or two about the trade.

Maybe she hadn't known a thing about what her husband had been involved in.

Did she know the things he had wanted to say?

I'm at the level which knows all the things you have to know to make a major decision.

You know, all the things which a growing child might question.
