I have never thought about special talking techniques to improve social connections.
This video tells us very important thing that our relatives are the main motivation which changes our behavior for better. It could be wrong for somebody, but I have a good example from my life. It is my husband. Of course, he is not a perfect man and has many bad habits. But, I should admit that he tries every day to be better for me. Before we met, he was "mother son" without idea of his future career and possibility to have own family.
