Read the passage.

I found out what a Rorshach is. It's the test I took before the operation—the one with the inkblots on the pieces of cardboard. The man who gave me the test was the same one. I was scared to death of those inkblots. I knew he was going to ask me to find the pictures and I knew I wouldn't be able to. I was thinking to myself, if only there was some way of knowing what kind of pictures were hidden there. Maybe there weren't any pictures at all. Maybe it was just a trick to see if I was dumb enough to look for something that wasn't there. Just thinking about that made me sore at him.
