I find each realtionship highly intrguing, be it a mother-daughter, husband-wife, daughter-in-law-mother-in-law, the list can be endless, if we include brother-in-law's brothers-in-law.
The mother-child relationship starts in the womb. From a small embryo to slowly developing each part of the body, each organ and then transforming into a full fledged human body - all inside the womb - a small bag, surrounded by water. It is one of nature's wonders - a life inside another life....and then bringing this tiny life into the outside world.
