For Kalani's 10th birthday, he wanted to do something special. His biological dad hadn't been a big part in his life, and his step-dad has been the man who loved and supported him through all the tough times, a real dad. So at his birthday Kalani stopped everything to read his step-dad a heartfelt letter about what it really means to be a dad. And when he asks his step-dad to officially adopt him the tears started flowing. This is the sweetest!
