Google Autocomplete suggests, in real time, ways to complete your searches.

The fourth item in the screenshot above may be specific to my own Google history, because lately I’ve been searching for this article about an affair with a professor whenever I want to send it to someone as a great example of confessional first person writing. (Google autocomplete is also informed by your search history.) So I’m curious if readers’ results vary. Give it a shot! Then leave it in the comments.
