Lesson
1 Speaking lashon hora about someone in front of them is very serious,
even if you are mentioning their faults to criticize them constructively.
Corrective comments should be delivered privately. Offending someone in public
causes humiliation and mortification and is lashon hora.
Lesson 2 One is not allowed to say lashon
hora even as a joke. - even if its said without hatred and without the intention
of hurting/degrading the person. saying "its just a joke" doesn’t change its
status.
