Hereorthere (take 2, although I don’t quite understand what was wrong with take 1):
You need to teach in an effective way. Not in volume. Volume means nothing if the message is NOT being recieved. Sometimes, the more you say the less you say. Why aren’t kids in school 12 hours a day? Because they can’t learn that long. After a while, nothing really sinks in. That’s why kids are in school for shorter hours – they can learn and absorb better that way (obviously, a balance on both ends).
When every speech is about tznius, people stop listening. People don’t take it seriously because its become the catch all of everything, rather than have people take their own personal responsibility.
