Thank you all, and thank you especially David. I checked with the French Consulate here in San Francisco and according to their pre-recorded front end for visa inquiries, it is what everyone has said. Just for tourism, 90 days or less, no visa required; that's what they say. My French friend is still being cautionary, but since I'm not leaving until mid October, I'll just track this on a weekly basis. But again, thank you all for your input, all of it was very helpful.
