A fun-loving grandma decided to go through with a long-running joke that she would get a tattoo on her 90th birthday – as long as all of her granddaughters did too. For some time, Rene Swearingen, from Stockton, California, had heard her grandchildren joke that she should get a tattoo to mark the milestone birthday. But when it came down to the big day itself, Rene had one stipulation: she would only do it if her granddaughters copied her. The joke had initially seemed funny to family because getting a tattoo would be so out of character for Rene, one of her granddaughters, Tori Hein, 32, said. Once the 90-year-old had made her decision on May 19, though, she and her four granddaughters started researching tattoo parlors in the local area. The group decided the would all get hummingbird tattoos, as hummingbirds are Rene's favorite kind of bird, which she watches out of her window. They then headed to Port City Ink, in Stockton, where Tori documented how she, her grandmother, fellow granddaughters – Olivia Swearingen, Jessica Ream, and Rebekah Lopez – and Rene's daughter-in-law – Tori's mom Anita Swearingen – all got matching birds tattooed on their arms.
