Callie stared at me, daring me to make a mistake, willing me to let her win.
Justin stood between the trophy and me as my greatest threat.
Monroe walked slowly down the corridor toward the math exam he dreaded.
Sam took the last seat in the front of the bus, spoiling my chance to plead with the teacher.
