There are very few people that actually realize that the word discipline comes from the word disciple.
Fewer still that understand that disciplining is about guiding and teaching; giving information, support, comfort, positive reinforcement and negative reinforcement when appropriate.
Or worse still there is a segment of the population that pretty much *puts up with their kids* or just does whatever THEY WANT with that kid until that kid either runs away or they through them out. Those are the ones that society REALLY foots the bill for.
