Stargazing
While some folks might have an idea of what they want when they decide to get a tattoo, others defer the responsibility of choosing a design to their tattoo artist. In many cases, the artist serves as a conduit between the buyer and their vision, to put it in unnecessarily technical terms.

Without knowing what to get, this person gave that responsibility to the tattoo artist, who asked what they enjoyed doing the most. When they said stargazing with their pet dog, the artist immediately knew what to draw, and just like that, this work of art was born!
