I can't feel confident in a doctor - or anyone who can't look at me when they talk to me. It was so peculiar how the doctor could not and would not look at me when they spoke to me. They looked away or at the ground - very odd! Also the time they had you wait seemed a bit excessive considering the office did not seem busy.
