I think parents are not taking it easy on younger siblings. If you think about it, if you are considered the perfect child, that puts more pressure on the younger sibling to be as good as you. For example, lets say you had a younger daughter and that you were the best soccer player ever. Your parents will want your younger daughter to be as good as you in soccer so they can feel like they accomplished something great. However, lets say shes a prodigy for playing an instrument but not a sport. Your parents will be upset with her and try there best to make her a great sports star. I'm just saying even if physical punishment isn't commonly done on younger siblings anymore, we still have physiological pressure that can bring any kid to tears.
Has this ever happened to YOU?
You say something that doesn't hurt their feelings at all, but they PURPOSELY cry, and YOU get yelled at, but then they say something so mean that it makes you cringe a little, AND THEY DON'T GET YELLED AT.
No, this hasn't happened to me. If it did happen, which it wouldn't, we have a thing called Child Services. Also, I don't see the point of this argument. You say this about younger siblings but then it seems you have changed the topic to child abuse. Also, if you cringed, hows that bad. We always hear or see comments that make us cringe, but that doesn't mean that its child abuse or anything, we all do it. Now, please, make an argument about the actual topic.
