Whatever was written on the paper, it must have some kind of political meaning. So far as he could see there were two possibilities. One, much the more likely, was that the girl was an agent of the Thought Police, just as he had feared. He did not know why the Thought Police should choose to deliver their messages in such a fashion, but perhaps they had their reasons. The thing that was written on the paper might be a threat, a summons, an order to commit suicide, a trap of some description. But there was another, wilder possibility that kept raising its head, though he tried vainly to suppress it. This was, that the message did not come from the Thought Police at all, but from some kind of underground organisation. Perhaps the Brotherhood existed after all! Perhaps the girl was part of it! No doubt the idea was absurd, but it had sprung into his mind in the very instant of feeling the scrap of paper in his hand. It was not till a couple of minutes later that the other, more probable explanation had occurred to him. And even now, though his intellect told him that the message probably meant death -- still, that was not what he believed, and the unreasonable hope persisted, and his heart banged, and it was with difficulty that he kept his voice from trembling as he murmured his figures into the speakwrite.

He rolled up the completed bundle of work and slid it into the pneumatic tube. Eight minutes had gone by. He re-adjusted his spectacles on his nose, sighed, and drew the next batch of work towards him, with the scrap of paper on top of it. He flattened it out. On it was written, in a large unformed handwriting:

I love you.

For several seconds he was too stunned even to throw the incriminating thing into the memory hole. When he did so, although he knew very well the danger of showing too much interest, he could not resist reading it once again, just to make sure that the words were really there.
George Orwell, from 1984
