Is 1 always 1?

I was just walking back w my sister. We were looking at the moon.
So i was just saying, the moon looks really pretty.
And she says 'no! That same crescent moon appears once every 15 days. How can it be pretty. its not like it appears once in a year!'
So i was thinking, is beauty relative? Is there absolute beauty?

I always tell my darling she looks pretty. But by looking pretty everyday, does that take any gloss off her beauty?
Nope.
Its novelty that eclipses beauty. Its the concept of relativity that kills beauty. Its the notion of 'over n over again' that corrodes beauty.
How can one thing that looked pretty to you before, suddenly not look pretty?
Nope. The person still is the same, and you haven't changed. Its just, perception.
Every once in 15 days, i see a crescent moon, i say its beautiful.
Everyday i see my girl, i say she's beautiful. You don't look any less beautiful just because u look beautiful everyday.

You don't have to up your game for the person you love, because the person who loves you shouldn't ever have to think twice about your beauty
