     "It hurts me more than you." and "This is for your own good." These are the statements my mother used

to make years ago when I had to learn Latin, clean my room, stay home and do homework.   

     That was before we entered the permissive period in education in which we decided it was all right not to

push our children to achieve their best in school.   

     The schools and the educators made it easy for us. They thought that it was right to be parents who take

a let alone policy. We stopped making our children do homework. We gave them calculators (计算器), turned

on the television, left the teaching to the teachers and went on vacation.   

     Now teachers, having taught many children who have been developing at their own step for the past 15

years, are realizing we've made a terrible mistake. Sharon Klompus is such a teacher who thinks her students

"so passive" and wonders what happened. Nothing was demanded of them. She believes that Television

contributes to children's passivity. "We're not training kids to work anymore," says Klompus. "We're talking

about a generation of kids who've never been hurt or hungry. They have learned somebody will always do it

for them. Instead of saying 'go and look it up', you tell them the answer. It takes greater energy to say no to

a kid."   

     Yes, it does. It takes energy and it takes work. It's time for parents to end their vecation and come back

to work. It's time to take the car away, to turn the TV off, to tell them it hurts you more than them but it's

for their own good. It's time to start telling them no again.
