Dear Dr.Hannibal Lecter, I understand you are now treating Harold Saxon. I don't know if he has mentioned me to you yet, but we were childhood friends and I think he might benefit from some group therapy with me. He tends to talk more when I'm there, and I could shed light on some of the more obscure things he says. I'm worried about him. The Doctor a.k.a. John Smith
Dear Dr. Mick St. John, I am writing to you concerning Donna Noble. She is a good friend of mine and many of the memories she no longer has are memories we shared together. I may be able to help her to recover her lost memory, but I am reluctant to do so without knowing how she is progressing in her therapy. Is she ready to hear about what happened that made her forget? I am sure I do not need to request this be kept confidential. The Doctor a.k.a. John Smith
