People can think and act while listening, including forming thoughts, interrupting, taking notes, or making tool calls before the speaker has finished.

“But our brain is thinking while listening.”

“So as I'm speaking to you, you're already forming your thoughts and if I'm talking for too long, you'll interrupt.”

“dropped me right or you might be taking notes in the back end right so you might be”

“essentially doing tool calls while I'm speaking to you.”
