Get the great-grandnephew-by-marriagemug. The culmination of life and love. Raised right, distance overcome. Unconditional even when tough and strong when faced with our world today. Gleaming oneness in a world so intent on separation.
Look at those guys. With the world how it is today, it is great to see people who are going to have a beautiful marriage.
