More than once did Elizabeth, in her ramble within the park, unexpectedly meet Mr. Darcy. She felt all the perverseness of the mischance that should bring him where no one else was brought, and, to prevent its ever happening again, took care to inform him at first that it was a favourite haunt of hers. How it could occur a second time, therefore, was very odd! Yet it did, and even a third. It seemed like wilful ill-nature, or a voluntary penance, for on these occasions it was not merely a few formal inquiries and an awkward pause and then away, but he actually thought it necessary to turn back and walk with her.
– Jane Austen
Pride and Prejudice, Chapter 33. While staying with her friend Charlotte, Elizabeth goes on walks in the countryside near Rosings and keeps running into Darcy. The two reluctant lovebirds are still tip-toeing around each other as they "unexpectedly" bump into each other in the park twice. But there may be nothing unexpected about it. Elizabeth lets Darcy know that it is her favorite place, so practically extends to him an invitation to be there.
