First time to swear at my daughter

Today I swore at my daughter for the first time.
She has it is her first month at Secondary school and I am trying to give her some responsibilities. one is to go to her music class and to come home straight after.

She had not appeared for over 30 minutes. Went to the place where I dropped her off and she was there ‘playing’

Blood boiled ordered her home and swore at her on the way.
I have lost the art of swearing etc after all of these years.
