The person who came out of the house a little later ______.

There was a fire in the middle of the night at a country house where there were many guests.
    They all rushed outside when they heard the alarm. They did not even wait to put on their clothes. Dressed in blankets and overcoats, they were standing watching the flames when another guest joined them. "Why did you people get so excited?" be asked, "Now look at me. When I heard the alarm, I got out of bed, lit a cigarette and quietly dressed myself. In fact I was putting on my tie when I thought it was not the best tie to wear with a shirt I had on. I took it off and put on another.  I did not lose my head at all. I never get excited in a difficult or dangerous situation." "That’s good," said one of his friends, "but why didn’t you put on your trousers?"
