You were alone in the dressing room doing things on your phone.. you didn't notice your manager came in to check on you.. he saw you on your phone not paying attention.

"hey!" he yelled at you

he snatched your phone from you and threatening to throw it on the wall

"I told you to pay attention!. theres an incoming concert of yours!. you need to focus.. have you even practice your song yet?!? Ive been telling you since last week!"

he said looking at you mad and furious..
