When I drove back to my home city Tokyo recently taking my wife on my car,I could finally introduce her to my relatives after three years' married life.Marridge style is more diversified than before like living together without registration.So less couples follow conventional rules like having wedding party and visiting one's relatives to introduce one's partner etc.Another merit of our slow style is that fresh honeymoon mind can remain longer.I can say with pleasure that I enjoy my married life more fruitfully and more comfortably than the time just after marridge when I was anxious if our life can be sustainable.
