I'm not trying to be mean and I'm sorry if I do, but your comment sounds a bit too harsh. You don't know if there's more to the friend's story. You don't know for sure if she's a spoiled child.

You say taking the phone away, giving early nights and not giving treats when kids are bad is not abuse, but that's your view. In many other cases it is abuse. Parents that take their kid's phone away and invade their privacy, abuse. Parents that take away their (only) means of communication, abuse. Early nights can mean not letting a child socialize with peers. Or even to send the kid to bed without dinner, and that's abuse. And no treats when the kid is bad... What is bad exactly? It changes and it can be anything if the parents decide it. And in the case of more than one kid, it can mean one of them has to see their siblings get treated better. So that's abuse, too.

It depends on the context and it varies. Abuse is not black or white. Abuse is not something you can claim when you check enough items on a list.
