I am a firm believer of corporal punishment. My kids require hindside dust removal services occasionally. Once I knock the dust off, they have a new outlook on life, at least for a little while. I do have to administer reminders.
My kids are aware of what happens if they don't obey me, and their teachers. They usually only have to be told once what is expected. If I have to tell them twice, they are due a reminder!
Good - I misunderstood you, then.
