I say semi because there were about 5 people in that elevator. I chose one person as a target. I chose an old teacher only because I knew that a teacher usually wouldn't hit me or curse me. I was extremely nervous because I felt bad for trying to make an old man uncomfortable and secondly, I didn't know what his immediate reaction would be. And so, I pressed all the elevator buttons that were on all ten floors. I faced the back of the elevator but faced the old professor as if I was very close. He looked quite confused because as the floor levels increased I was saying "oh that's my floor". He would then say that you are in the wrong direction. I would then say "oops, that's not the floor" and move even closer to him to the point where my arms were touching his. As people started to come down, I had the impression that they thought I had serious mental problems. When the teacher got to the floor level, he told me that it was very rude to play silly games in an elevator by pressing all the buttons, and that it was rude to stand so close of a man his age.
