A woman gave her beloved mother-in-law the ultimate surprise when she presented her with a tattoo of her name on Mother's Day. Marlen Zavala, 20, from Salt Lake County, Utah, has always been close to her boyfriend's mom, Elizabeth Guzman, seeing her as a daughter even though they are not biologically related. Since Marlen started dating her boyfriend around four years ago, she and Elizabeth, 39, have worked jobs together, spent time hanging out, and "have been through so many things together people wouldn't even image," Marlen said. Elizabeth was there for Marlen's first tattoo – and the 39-year-old even got Marlen's name tattooed on her body along with her biological children. That gesture really touched Marlen, and so, for Mother's Day in Mexico, she decided to return the show of love.
