Take the stairs

Along the lines of my smoking is bad for you outburst, I was in the lift the other day when a young chap got in and pressed the button for floor two. In my own impish way I said he should be taking the stairs. He received my comment in the spirit in which it was meant and suggested that he should.

I was only going to the fourth floor myself, of course; and could have taken the stairs myself really.
