In 1984, we could argue that the first event happens when Winston starts writing in his diary. Although there are no laws in Oceania, if the Party found out that Winston had bought a diary and intended to write in it, he would be severely punished.
At first, Winston struggles to find something to write. However, once he gets going, the words "Down with Big Brother" become his mantra. Winston, therefore, uses the diary to express his discontent and frustration at the Party's rule.
By the end of the novel, however, Winston is considerably changed. In the closing lines, for example, we learn that Winston no longer struggles with his feelings of rebellion. Instead, he has come to love Big Brother, and these feelings appear genuine.
What we have, then, is a major contrast between the first event and the last. Winston is no longer the secret rebel; he has been transformed into the ideal Party member.
