How do you ask your principal how he is doing in french?

Here are a few ways to ask your principal how they are doing in French, depending on the level of formality:

Formal:

* "Comment allez-vous, Monsieur/Madame [Principal's last name]?" (How are you, Mr./Mrs. [Principal's last name]?)

* "Comment va votre journée, Monsieur/Madame [Principal's last name]?" (How is your day going, Mr./Mrs. [Principal's last name]?)

Informal (if you have a friendly relationship):

* "Bonjour, Monsieur/Madame [Principal's last name], comment ça va?" (Good morning, Mr./Mrs. [Principal's last name], how are you?)

* "Ça va bien, Monsieur/Madame [Principal's last name]?" (Everything alright, Mr./Mrs. [Principal's last name]?)

Remember to adjust the level of formality based on your relationship with your principal and the context of the interaction.
