Smooth as sandpaper look like a contradiction, yet life always shows its truths in different ironies. Sandpaper looks rough, gritty, and not easy on the skin when you touch it for the first time. So, it is the same roughness that polishes, changes surfaces into something that's beautiful. That's the type of smoothness that isn't soft but it's transformative.
It's the instructor that criticism stings but takes you to perfection. It's the battle that takes away your fear until bravery hold naked. Sandpaper smooths not through softness, but through steady friction, that takes away anything that does not have anything to do with each stroke.
In a sense, some people can be like that: abrasive at first, but they leave you better than they found you. Smoothness, then, isn't always silk or liquid. Sometimes it's sandpaper in strong, deliberate hands.
