Salut!
1. I don’t see what you mean.
2. I simply do not understand why he still isn’t seeing him!
3. Do you have any idea why she isn’t believing me?
4. I’m afraid I can’t have lunch with you today.
5. Why are you so upset? Who are you thinking of?
6. I don’t think you know what you are doing here!
7. I’ve never met her. What does she look like?
8. What is it? What are you looking at?
J’espère que j’ai pu t’aider! Au revoir!
