Read the passage from "Stage Fright" by Mark Twain. I recall the occasion of my first appearance. San Francisco knew me then only as a reporter, and I was to make my bow to San Francisco as a lecturer. I knew that nothing short of my compulsion would get me to the theater. So I bound myself by a hard-and-fast contract so that I coul not escape. I got to the theater forty-five minutes before the hour set for the lecture. My knees were shaking so that I didn't know whether I could stand up. If there is an awful, horrible malady in the world, it is stage fright -- and seasickness. They are a pair. I had stage fright then for the first and last time. I was only seasick once, too. It was on a little ship on which there were two hundred other passengers. I -- was -- sick. I was so sick th there wasn't any left for those other two hundred passengers. Which two items does the writer compare?​
