Read the following passage and answer the question. PASSAGE: HOW TO SNEAK INTO THE HOUSE AT NIGHT The first step i take is bringing my key along with me. Obviously, I don't want to have to knock on the door at 1:30 in the morning and rouse my parents out of bed. Second, I make it a point to stay out past midnight. If I come in before then, my father is still up, and I'll have to face his disapproving look. All I need in my life is for him to make me feel guilty. Trying to make it as a college student is as much as I'm ready to handle. Next, I am careful to be very quiet upon entering the house. This involves lifting the front door up slightly as I open it, so that it does not creak. It also means treating the floor and steps in the second floor like a minefield, stepping carefully over the spots that squeak. When I'm upstairs, I stop briefly in the bathroom without turning on the light. Finally, I tiptoe to my room, put my clothes in a pile on a chair, and slip quietly into bed. With my careful method of sneaking into the house at night, I have avoided some major hassles with my parents. Question: which method does the author apply in the above exposition?
