Dear Dental Hygienist
Dear Dental Hygienist,
Please stop talking to me. I can't answer your questions when you have your hands in my mouth. Not that I would want to if you didn't. I understand that you are trying to put me at ease, but this is a business transaction. I don't need you to get to know me and I don't need to get to know you. Just get in there, do what you have to do and let me leave.
Sincerely,
Patient
