because you let her...grow a pair and enforce the rules. You're the parent not the friend.

It’s easy to convince someone who has no intention of actually following through.

Because you realize your rules are stupid and arbitrary. If she took "con" against your rules, she'd shred you.

She gets it honestly. Since she’s smart, get inside her head and work from there. You can be firm without being a dictator.

She learned all those debate skills from you. She will become a great lawyer.

If it's not hurting her, maybe having a slightly bigger dessert and an hour later bedtime is a good thing. You don't need to enforce rules unless they're stopping something bad from happening.

Let me guess, it’s her big soulful eyes look that gets you every single time.
