It seemed that whatever bolt he may unlatch, and whatever latch he may unbolt, the door seemed decidedly resistant to actually opening! He half turned to look at the querent, his own confusion evident on his face, "Did someone-- I don't know, look, do you live here? I'm afraid my intrusion is most unintentional, but I think there's something wrong with your door!"
Simon was slowly growing more agitated with the situation, beginning to put some of his weight into his continued attempts to convince the door to open. It wasn't locked in any way he could see, and yet with all his shoving and pulling the wood barely seemed to shift a fraction of an inch. It was as though he was fighting against a marble wall.
