All for One
Disciplining children is not easy; parents often find themselves desperately looking for disciplining methods that will not leave their kids scarred for life. And the job gets much more complicated when siblings are involved, as punishing one for all or all for one can be unfair and drive edges between them.
Maybe this person’s parents were trying to teach all the siblings about the consequences of certain behaviors and mistakes even if they didn’t do it, you know, like “two birds, one stone”? They probably didn’t anticipate it would annoy them so much that years later, they would share it all over the Internet. So whenever you discipline your kids, just remember social media exists.
