Donny, your 12 year old, is a bit of a latter day Huck Finn. Although quite capable, he is not the keenest student in the world. Twice this term he has skipped school and gone to fish at the creek only turning up at supper time. He is perfectly happy with his own company. On each occasion you signed him up for Saturday detentions at the school and drove him there to make sure he showed! You warned him after the last time that he would be spanked severely if he didn't have a very good reason. Well, its happened again. You left work early after your spouse rang to tell you the school had been on again and found Donny here.
Donny tells you in his own disarming way that it was just too nice a day to be stuck in a classroom.
Is that any excuse or do you make good on your threat and how?
