"You may not believe it when you see it on TV, but it does hurt when your daughter yells "You never let me have any fun, I hate you daddy!" and runs to her room."
So what? You're her parent, not her friend. Being a parent means doing whats in their best interests even if their 9 year old brain can't yet understand why and doesn't like it. Also part of growing up is being told you can't do stuff and not liking it.
And yes, I do have a kid.
