Dear R (backup T),
Sorry if that email was sort of harsh and formal, but I really did feel pressured into agreeing to let you talk to Dr. T today. I don't understand why it's so important you say something to him about it. Yes, I was talking to you about him, but I was trying to figure out how to approach some of that stuff with him. Not for you to tell him. I worry you may not be willing to work with me again after I revoke that, but maybe it's for the best?
