I agree.
Make sure that you log each manuever, and in the back record the ground lessons. Make sure you have a copy of a passport or birth cerificate and that you log in his book that you have verified citizenship. If you dont, the TSA could fry you.
Cover everthing as written in part 61,and dont EVER sign off anything you didn't do. That signiture has powerful authority, but with that comes responsibility in the same degree and remember that you will be held accountable for it in the event of an incident or worse.
