Because sometimes people give too much attention to physical beauty and forget that being beautiful is not always about visual aesthetics.
The pursuit of beauty is a hard chase. Because we are blinded. We stop and look (and criticize), and that is all there is to it.
What is ugly then? Why do we say someone is ugly? Ugly is demeaning and no one deserves to be called ugly, unpleasant, and unattractive.
We are all beautiful. We just choose not to acknowledge it.
