Furiousness

I sent an email to my dissertation supervisor and my head of department today concerning some problems I have had with the project. The contents of the email was personal and (I considered it to be) confidential.

My supervisor emailed me back with a very supportive email but he has copied two other people in on his reply, leaving my original email at the bottom. If I had wanted them to know, I would have sent it to them...

I am furious that my confidentiality has been breached. I just assumed he wouldn't forward it on to anyone. ARGH>
