Guess the Profession
Don’t ask questions, make statements. This is a good rule for getting information — it forces them to give you real information and ask why you think so, which leads to even more interesting cold reading possibilities.
You look like a school teacher (or a lawyer)
She’ll ask why
Teacher
There’s an aura around you like “I’m going to save the world”
Lawyer
You have greedy eyes
Don’t limit yourself to this. Make your own conclusions based on your observations.
