This guy I met last night - I feel like I've known him my whole life. The way he talks about Coltrane, Miles. I didn't realize that there was someone who loves jazz more than I do. I guess unicorns do exist after all.

I had an epiphany last night. Went to the light show and realized that if you love something enough, you can make a living out of it. A true unicorn encounter.
