Dear Patient, One of the perks of my job is getting a close-up view of people’s tattoos. Some are beautiful, some whimsical, and recently I saw one that got me thinking—it was a set of familiar symbols tattooed onto a patient’s arm. It took me a few seconds to recognize the collection of shapes and lines, because I usually see them on clothing tags—they were the symbols indicating a garment’s laundry care instructions.
