Humanity
Do we forget that we are human? Is it a product of where we live? Our society? Is it cultural? Do some cultures have a better grip on what it is to be human? Or how to live life? Does the sound of a cello not stop your heart from beating? Human tears - salty human tears. The sound of a man's baritone voice, unwavering as he belts out a ballad of a lost love. A baby. People in love. The sunset. Dancing so much you get dizzy and lose yourself in your partner's arms. Jumping in a cold lake. The sun on your bare skin. The eminent beat of a drum. Or a heart beat! Freckles. The way fire dances in the night. A good glass of champagne. Stories you get lost in. The smell of a jasmine vine on a warm Spring day. The physique of an athlete. The foam of a latté.
I guess this just turned into a short list of the countless things I find beautiful. You're also on that list :)
Don't ever lose your innate ability to appreciate life.
