Gabriella Guardado, a 22-year-old registered nurse from Florida, clearly has a really cool step-dad, because he acts grateful and excited to find a pen in his birthday gift bag, not realizing the real gift was the adult adoption form underneath. It takes David Lynde a moment to realize what his daughter has just handed him, but once he does, the emotions come pouring forth.

Gabriella had wanted Lynde to adopt her since she was 12, but her biological father would not sign off on the papers. She gave up when she turned 18, unaware that adult adoption was a possibility. "I did research and found out that I could do that without the consent of my biological dad," she told the Daily Mail, and she prepared the paperwork as a gift for David's 53rd birthday.
