I smiled at the smile of an old lady who had that smile in the eyes, like inside, she was still young. She smiled and thanked me for making her coffee and serving her her muffin and her chocolate slice and her milkshake with added thickener to stop her brother (I'm assuming he was her brother) from choking. He was even older than she was. He shuffled about in one of those wheel zimmerframe things, and they spilled too many muffin crumbs on the table and were too far past their prime and she was too sweet for all the horribleness and sadness not too far ahead them.
But as she left, she smiled. A proper smile, in spite of everything. Wrinkles at the corners of the eyes, the whole smile deal, and that made me smile. It was a sad smile. It was a smile of gratitude. It was a smile that said, thank you.
