Attorney Client Privilege
This is a funny one from my personal life. I’m a lawyer, and my brother was selling a script to a network and hired an entertainment lawyer to go through the process. I was talking about it with my brother and asked a few questions, mostly just out of curiosity. He said, “I can’t tell you, it’s privileged”. I had to explain to him that he can tell me, his lawyer can’t.
