I would be a little tougher at least. geez. I mean, I really Don't like it when parents don't disipline there children because apparently the "love them too much". Well, thats a great way to be taken advantage of by the child you say that too. 
I think at least. It annoys me though because they don't ground them or do anything and if they do they usually don't follow through with it. lame. geez, at least do something., other than livving out the rest of your life controlled by a child who has no respect for you. 
But if you think about it, making sure that your kids aren't spoiled brats is better for them in the end. I guess.
