Exterior beauty is viewed like the average individual passing a painting.
They barely understand meaning, but seem to conclude that the painting is beautiful.

Interior beauty is ignored like the average individual passing a painting.
They understand the surface, they see it's beauty, but the exact story behind the painting is unknown and worthless.

We focus on the exterior, make a decision and leave, but forget that the interior is what will reveal itself louder than the most bombastic exterior.
