it was my turn and i was called up to sing , while singing , i noticed my trouser zip was full open because it had spoiled . it was really embarrassing and i felt really ashamed of myself im sorry . i can imagine how you felt ! hopefully you hit a home run ! yes , i had to give them a signal so i can leave the stage thats something i would never forget . hopefully you get another shot at it .
Inadvertently exposing private body parts in public triggered the feeling of shame.
