One of the things I like to keep with me in my book bag I travel with is a small sketchbook, a basic shapes drafting stencil, and a fine black sharpie. Theres something about drawing lines and doodles in black ink that is so meditative and relaxing.
I completed these while waiting in the emergency room for 6+ hours. It even struck up a conversation with an elderly lady and her circumstances with her husband who did pass away that night before he was even admitted to the ER.
It's a night I won't forget easily. Art has a way of capturing memories within the pages.
