Here's a little cautionary tale:
Once upon a time, there was a boy who just couldn't manage to be on time. He was given lots of rope to hang himself, having many opportunities and warnings prior to our last meeting. He assured me that he would, indeed, be there promptly.
Alas, the boy was yet again unable to find himself at the proper place in the proper time.
Eleven minutes late, he was, so for each minute late - ten strokes of the cane. Applied immediately upon his arrival.
One hundred and ten strokes later (and still with a two hour spanking ahead):
I'll let you guess the moral of the story.
