I loved how my hand found its perfect case in yours when we were in some dense wood outside Bergama and i was kneeling because i had to puke so bad after lunch in a dodgy bistro. While i was gagging sweating tasting my own vomit crying, i was so aware of your tender fingers securing their grip. I could neither look at you nor tell you how much it meant. This little gesture. You can be such a sweet person.
we are sensitive, fragile, self-centered people sometimes, forgetting that there's worse in the world than our offended little souls, adversities so scandalous and heart-breaking, they make our issues look small and our so-called hardships void.
Why can't we be a little lighter, a little more in tune with everybody, a little less tight
