'I see that I'm interrupting you. You're writing.'

'No, I assure you.'

'But you've got a pen in your hand.'

'It can wait—a matter of no importance. Sit down.'

'Now, you'll tell me if I'm in the way?'

'My good man, why are you talking like that? Why should you be in the way?'

'Well, if you're sure you've nothing to do, may I stay to supper?'

'To supper?'

'But I see that I'm in the way.'

'No; I tell you you're not in the way. And you're going to stay to supper.'
