Walking back from the post office, I see a young woman approaching from the opposite direction. She, like 90% of San Franciscans, is holding a black square object in her hand. She is gazing at it as she walks and smiling sweetly, fondly. She has clearly gotten a text from someone she loves.

She then raises the object to her mouth and takes a large bite out of it.
Oh. Um, so not a phone then.

No, what we have here is a woman who has a tender affection for brownies. Long may she reign.
