even Bible taught us a little punishment is needed..

as a matter of factor...

in this case, it is only showed the foolishness of the teacher, not the punishment itself...

in bible, it says 'chastening' is kind of expression of love, and christrian kid should be gratefull to it..

in other words, without love, the parents or teacher would rather give them a DS and have a good time for themselves... it is much easier...
