How should I consider a possibly rude reply from a potential PhD advisor? I am in my first semester of my applied math PhD program in the United States. The professor (potential PhD advisor) of the course I am auditing has replied to my question about the schedule for the final project:

I mentioned several times in the chat box in class. Did not you attend or did not you listen?

I had honestly not remembered that this was done and so it is my fault for not listening properly. However, I am interpreting this reply to be quite aggressive or rude. Should I no longer consider this person to possibly be my research advisor? How does one handle such a reply?

Thank you all for your advice and general comments. They have very much helped me.
He/she is probably very busy, and has repeated the same message probably N times.  Also, we all assume students will find the required information by themselves.  Nowadays, I find that students simply don't spend the time to look for information.  Their first instinct is to simply to message me, and hope that I will solve their problems for them; this is very similar to a kid asking their parents, can you please clean up after me? It is ok if you are 2 year old, but not OK after a certain age.
As for whether the professor should be a supervisor, you should look at whether he/she is successful in supervising students.  Yes, he/she may not entertain trivial questions and tell you off, but that may mean you need to work independently and at a high level.
