Addendum – It is now eight in the evening. The sun has almost set, but I am still here at the stones, and I have resolved to stay here all night if necessary. I must get through that door!
Never before have I felt so obsessed by something so simple. The idea that a simple door could keep me from making a potentially vital discovery is infuriating, and I am starting to feel my blood boil. I am no locksmith, but I feel that I am an intelligent man and I am absolutely certain that I will not be beaten by whoever put this door in place. The longer I have to work, the more frantic I become, and my frustration is starting to boil over. I have even begun to mutter and curse under my breath, and I fear that anyone who happened past this site right now would assume me to be a madman.
The other problem is that I am becoming increasingly certain that someone or something is watching me. Even as I set these words down, I feel as if they are ridiculous, but the sensation persists: whenever I have been working on the door for more than a few minutes at a time, I begin to feel as if there is someone standing a little way behind me. I force myself not to look, but eventually the sensation becomes too strong and I turn, only to see that there is no-one. Unfortunately, this situation is getting worse, and my attempts to stay calm are becoming more and more difficult.
I must simply focus on the task at hand.

Addendum – I don't know where he's hiding, but I'm certain that there is indeed someone down here with me, someone watching my every move and probably laughing at my inability to get this door open.
I must simply ignore him. I shall not add any more updates to my diary tonight, since I have to work without interrupting.
