"We have been together now over six years, sir, so I suppose I know you a bit by this time.

I could see there was something wrong directly you came on board." "Mr.Franklin," said the captain, "we have been more than six years together, it is true, but I didn't know you for a reader of faces.

You are not a correct reader though.

It's very far from being wrong.
