I've always tried to approach my own art without thinking about why. I want to create art the same way a clam creates a pearl. It just does.
But it was also true that much of it was for her. She was the first person I'd show anything... a doodle, a joke, a music mix. It was also to make her happy because life's not easy. She took meds for depression but I could make her laugh.
I'm still laughing, but mostly in wonder at how it keeps hurting.
