Half Life 2: Concerned?

Many of you who will visit this site will wonder to yourself: "What is up with the 'concerned' part?"
There's an answer for that. Seeing as Dr. Breen is the administrator character of Half Life 2, I decided to take a quote from him, after reading a letter sent to him signed by a concerned citizen. He then continues to call the citizen 'Concerned' as if it was his/her's real name. People who catch that part out in the beggining of the game will understand it better.
