Please Say/Whisper The Words Out Loud
Lesson 1
Parents should educate their children about shmirat halashon. Habit is one of the main reasons why people are so careless in speaking lashon hora. If a parent would train their kids in this from early on, it would be easier for them to avoid speaking lashon hora when they grow up.
Lesson 2
The laws of onaas devorim (verbal abuse) are based on the subjective response of the person you are talking to. Even if many others wouldn’t care, if the person you say it to will be distressed, upset, angry or offended, don’t say it.
