SCENARIO: Before class begins, Lethargic Larry walks by, and you notice a rather pungent, unusual smell. You realize that the smell comes from alcohol or marijuana. Larry meanders to a seat in the back and sits quietly, placing the correct book and notebook on the desk. He looks just as attentive as other students in the class, which is not saying too much. A couple of students who sit near Larry notice the smell, too, and start giggling. One whispers something to another student sitting away from Larry, who also lets out a snicker. It stops there, but these students keep glancing at Larry, who sits there not taking notes and not participating (which is not unusual for many students in the room). EXTENDED SCENARIO: Lethargic Larry shows up for the fourth time smelling like marijuana or alcohol. Students who sit near him roll their eyes and move away as Larry grabs the same desk in the back. A couple cough loudly while a couple more hold their noses and look at each other
