Actually, I’ve often found that in school kids ridiculed lashon hara hours and didn’t gain a thing from them other than to choose “4-5 am” so they would technically be LH free.
Mother’s Day may remind people who aren’t so makpid on Kibbud Am that its important to respect your parents. It may be a stepping stone. Don’t be so quick to dismiss it. If nothing else, it means a person is striving for Kibbud Am once a year, rather than never right?
