As with any mode of academic writing, the introduction culminates in a thesis statement.
You've placed your reader in the world of your subject, and skillfully guided her toward a specific attitude regarding this person's situation.
Furthermore, it could hurt your credibility if the reader feels you are slanting facts for the benefit of your argument.
Whenever using narrative examples, stick to the facts, and keep yourself removed from the story. As you wrap up your narrative, you can then comment on how the narrative relates to your attitude toward your subject.
Now, you explicitly state your position and how you intend to prove it.
For example, if you are proposing that this athlete is an innocent man who has been reacting justifiably to a media onslaught, you must say that, and then list the ways in which you plan to prove it.
If for example, you are writing an essay about coffee, then you may start it off like this: "Half of Americans are drug addicts as caffeine has become the most widely used drug in the world." Another way to compose a topic sentence is to separate your individual ideas.
For example, "Coffee is an addictive drug because it stimulates the nervous system, causes increased alertness, and can be addictive." This allows you to create paragraphs around these ideas and lets the reader know what lies ahead.
With shops such as Starbucks popping up on every corner, coffee has been pushed into the limelight.
Due to its growing popularity, many people have become dependent on coffee to get through their day".
