You can call me Dr. Cheung

Snippet of an e-mail I got today:

Hello Dr.Cheung
  I am a graduate student of Virginia Tech.

*Blah, blah, blah. I'm asking you about something that isn't your research. I don't know how to read and I'm too incompetent to find the right source. Please help me*

I guess I'm done my PhD now that I'm a doctor. I guess my application for an honorary doctorate went through.
