A young woman came in wanting a belly button tattoo. When I asked what she wanted in her belly button she said, "I don't have a belly button, I want you to tattoo one on me." She was born with malfunctioning organs and as a newborn the doctors had cut her open from sternum to tailbone in order to remove said organs and then stitched her back up leaving two small holes in her side for waste. She was perfectly sealed up apart from those two holes.
After I had tattooed a dainty little grey and pink navel she got up to have a look, tears welled in her eyes and then she did a little dance as she squeaked, "I've never felt closer to my mother!"
The shop got a little dustier that day. That was just about the best feeling I've ever had after completing a tattoo.
