What am I?

Patient (talking to the attending while pointing at me): Is she a student?
Attending: Nope, she's a doctor too.

...later in the conversation, while the attending is explaining something to me...

Patient: I thought she was a doctor?
Attending: She is, but she's also learning.
Patient: So she is a student?
Attending: No, she's a doctor.

Don't worry kid, I don't really know what I am either.
