hi !
1) Would you use "tu" or "vous" with the following persons
2- Mr Bernard = vous
3- Melle Fournier = vous
4- Thomas = tu
5- Sylvain = tu
6- Doctor Martin = vous
7- Sylvain = tu
8- Marie-France = tuÂ
Usually when you call s.o by his first name, it's s.o you're friend with, so you call him "tu". If you call him by his last name, his surname, it's a person you know less; so it's "vous" (it's a question of courtesy like the Usted and Ustedes in Spanish if you ever study it !!!)
hope I helped !!!
