I feel like I'm going to get an attitude with my family doctor.
Why do you want to get an attitude with the doctor? What will you do?
I don't like going to the doctor. I'll just stare at him with a blank face and say nothing.
You shouldn't act childish to a family doctor. If you don't like the doctor then you should see a new one.
Dude, stop being lame. I'm going to do what I want to do.
Aren't you going to the doctor for help with your health? If you want effective treatment from the doctor you'll need to talk to him, and tell him about your symptoms or concerns. You'll have a much better experience if you participate in the appointment.
