I am an introverted person, unfamiliar with the world, sometimes misunderstood and harmless. What if I'm rude? Just graduated and ready to go to work, afraid of being misunderstood.
You can explain, if there is no chance to explain, you can write a note to tell him; I'm sorry, coach, but I think I have the right to wake you up I know you worked hard, but I paid for it after all. I'm not here to practice driving and waste time. Please forgive my rudeness.
