when my love for you quivers between caution and bravery , when i am too full of joy to be either brief or circumspect , this is when i glide through the alley that separates dormitory from classroom and brazenly stride down the path past the cafeteria in time to dance with the night watchman at the front gate-zigzagging between entrances , climbing up the fence and back again , waiting in shadow as he walks by oblivious .
