I bet poor Miss Badcock really wants to get married! At least her name's not Amy Shannon Smith. Why does Yoga ruin the day? I would think for most kids it would be relaxing.
Well, it's not really a relaxing thing if done in a school for kids or teenagers, it'd be more of a discipline thing.
I remember when my school forced us to stay in an extra hour and a half for extra-curricular activities.. school finished at 6pm or something. It didn't last long, too many complaints.
