A time where Bruce Lee introduced himself strongly and did not give in to fear:

One day on campus, Bruce Pulled her into an open office in Parrington Hall on the pretext they could study there in privacy.

It turned out to belong to Theodore Roethke, the university's internationally acclaimed, Pulitzer-Prize winning poet.

When Roethke walked in and caught them, he declared "I'm Roethke, the poet!. What are you doing in my room?"

Amy froze, but Bruce stood up, walked right over to him, and stuck out his hand.

"I'm Bruce 'Sifu' Lee, kung fu master. Good to meet you."

“What is kung fu?” Roethke asked.

Delighted by the question, Bruce went to the chalkboard and launched into a fifteen-minute lecture on kung fu, complete with diagrams and an explanation of the principles of yin and yang. Amy wanted to crawl under the door, but Roethke was mesmerized.

When Bruce finished, Roethke said, “I think I understand. Thank you. Please come back anytime you want to talk more about kung fu.”

The next day, Roethke recounted the story to his class: “I met a young man, and he is supposed to be a master of the martial arts. He seemed pretty lethal.”
