'Certainly,' she said; 'go and take some exercise, both of you. It's much better for young people than tea-drinking. And see here, my dear! I thought you were very sensible not to dress for dinner last night, like those silly young fools opposite. Silly young fools I call them. Now, take my advice, and don't let them persuade you to do it. An Atlantic steamer is no place for bare arms. Now run away, and have your walk, and Mr. Mafferton will see that you're not blown overboard.'

Mr. Mafferton hesitated a moment. 'Are you quite sure, he said, 'that you wouldn't prefer the tea?'

'Oh yes, sir!' I said; 'we always have tea at half-past six at home, and I don't care about it so early as this. I'd much rather walk. But don't trouble to come with me if you would like some tea.'

'I'll come,' he said, 'if you won't call me "sir."' Here he frowned a little and coloured. 'It makes one feel seventy, you know. May I ask why you do it?'

I explained that in Chicago it was considered polite to say 'ma'am' or 'sir' to a lady or gentleman of any age with whom you did not happen to be very well acquainted, and I had heard it all my life; still, if he objected to it, I would not use it in his case.

He said he thought he did object to it—from a lady; it had other associations in his ears.

So I stopped calling Mr. Mafferton 'sir'; and since then, except to very old gentlemen, I have got out of the way of using the expression. I asked him if there was anything else that struck him as odd in my conversation kindly to tell me, as of course I did not wish to be an unnecessary shock to my relation in Half-Moon Street. He did not say he would, but we seemed to get on together even more agreeably after that.
