How do you know when a carpenter is nervous?

You might notice a carpenter's nervousness through subtle signs such as fidgeting with tools, hesitating in their movements, or displaying a lack of focus on the task at hand. They may also avoid eye contact, speak more quickly or quietly, or show signs of frustration or uncertainty in their work. Additionally, if they frequently double-check measurements or ask for reassurance about their techniques, it could indicate that they are feeling anxious.
