Welcome back ladies and gentlemen of the internet. We're all familiar with the phrase 'kids will be kids.' They're not fully developed, and it's obvious that we should give them excuses for certain behaviors. Now, there's definitely a line, and there are things even young kids can be reprimanded for doing. Without proper discipline, kids that get away with misbehaving grow up spoiled and cruel, even narcissistic. It's important to discipline children appropriately.
In this Reddit thread, the original poster (OP) is a woman who's an aunt to three young children under 10. Her sister comes over for a visit one day, bringing her nieces and nephews as well. Immediately upon getting inside, they start destroying the home in completely animalistic ways. They destroy the carpet, furniture, and even draw on the walls. This ultimately results in OP's sister's children being uninvited to her wedding. You'll have to read the full story for all the juicy details.
