One day, Jack was in the hallway of the laboratory, chatting with a friend named Felix. Suddenly, he noticed the main researcher of the laboratory, Dr. Zander, standing nearby. Dr. Zander was accompanied by a teenager.

"Felix, do you know who that person is next to Dr. Zander?" asked Jack.

Felix replied, "Oh, that's Freud, the new researcher. Why? Are you interested in meeting new people again?"
