Teaching discipline and respect starts with the parents/guardians who show self-discipline and respect to themselves as well as to others. Parents should understand that they are their child's first teacher--and daily teacher--when it comes to life in general. The teacher has them for 6 hours while the parents have them FOR LIFE.
Children are observant when parents respect their elders or show respect to others. The kids also learn discipline by watching their parents who not only "preach it" but show it in their daily lives.
There's no way we can keep out technology from our children's lives but we can certainly teach them our values and morals everyday. As parents (aka LEADERS), we have to go back to teaching our kids good manners, respect, politeness, and self-discipline. However, most parents have to understand that teaching them these things doesn't work until the parents actually do it themselves!
