Yes, study him, that is a more worthwhile endeavor than trying to impress him. It’s almost 11 am your time and you are having him over in a few hours then, the afternoon. Probably going to be a visit of no consequence, like you wrote, you don’t expect to see him in the next ten years. So this visit is of no practical significance to you, makes no difference. Nothing to lose, really, so you can make anything of it, use it to practice anything you would like.

Will you offer him tea and a biscuit?
