LOL - when I hear, "There's no such thing as perfect!" I respond, "Really? You sure?" If whoever decides to engage, I invite them to ponder...
1. Their origin (where they came from). Do they consider whatever it is they 'came from' to be perfect. For simplicity I'll clarify with, "Do you hold the belief that something called God made you."
2. If yes, then, "Do you hold the belief that God is perfect?"
3. If yes, then, "Are you more than God? How can you be anything less than perfect?"
Perfection is never an end-game. It's the game with never-ending destinations.
