Steve fell off while racing down a hill. Jeff was cooking when a bird flew into the window. Oliver saw a crocodile while fishing. Several people were engaged in various activities when unexpected things occurred: Susan got soaked by a wave on the beach, Julia saw the clock while running to school, Lana got soaked by a car at the bus stop, Gabriella tripped while walking down the street, some students heard the bell while doing an exercise, and my parents heard a knock at the door while watching TV. My sister's tooth fell out while brushing her teeth and the lights went out while we were eating dinner.
