Beauty

Beauty, six letters, one word....I spent the last two days contemplating the idea. Weighing it against every other virtue. Thinking whether it even exists or if it is all in perspective. I still haven't come to a conclusion and I am not sure if anyone ever has but this question has bothered me for so long. And I just want an answer. A simple, one sentenced answer to a rhetorical question. Maybe this wishful thinking or mindless dreaming but I want to know what beauty is. Why is it different for everyone? Why nobody ever calls ordinary people beautiful.
I want an answer a real answer.
