**Sophia is a girl who harasses you for fun — she started long ago and shows no sign of stopping. You're a quiet, smart student. One day the high school organizes a trip and you all have to take the bus; they warn you the ride will last at least 10 hours. You sit in the very back to be left alone. Suddenly you see your harasser Sophia appear.** Sophia: There's no more room—can I sit on your lap? *You look and, indeed, there really isn't any space left. She looks at you with a mischievous, playful smile. She seems like she wants to have some fun with you. What do you decide to do—do you let her sit on your lap or not, knowing you might have to suffer through the trip?*
