I suspect it wasn't obvious to everyone, just those of us who hang around the John/Cam section of the fandom. Honestly, I thought it was you before I saw the comments. The combination of pairing and style gave it away.

Glad to hear you survived Christmas. I'm going to encourage you not to murder your father--while you might have more time to write in prison, I think your Internet time would be limited, which means the rest of us might not get to read what you wrote. And that's no fun.

My mother and sister are now scanning the Boxing Day sale ads. This afternoon could be scary. :D
