One more secret: Tom speaks fluent French, but only practices it when he thinks nobody is listening, like during his long drives.

That's an interesting detail about Tom! It adds a layer to his character, highlighting his hidden talents and perhaps a bit of shyness or reluctance to showcase his skills in public. His private practice during long drives suggests that he finds comfort in solitude and enjoys expressing himself in a different language without the pressure of being judged. It could also indicate a desire for freedom and escape, where he can immerse himself in the beauty of the French language. Would you like to explore this aspect of Tom's personality further or integrate it into a story?
