Like a dairy cow in the milking barn. After awhile it becomes routine and one knows what happens, what comes next and what to do. The nurse knows me as does the examiner as does their office manager. I walk through the inner office door. They hand me the cup. I know where to leave it. I head for the weigh in scale and even slide the weights without prompt. Next is the eye test machine. Squint. Then the interview and exam and finally an EKG and then checkout payment. Text book. Every 6 months. A well known drill by now.
