Lets just throw out for the time being that nature has embedded within us the instinct to procreate, and with the possible exception of some single celled organisms and the Virgin Mary it takes two to accomplish this. Lets not get too crazy in dismissing the instinct to reproduce or the fact that the act of reproduction can be incredibly fun, but there are other reasons men and women feel the need to be together as well, companionship probably being the best known of them.
People get lonely, that’s the plain and simple of it and as such we search for others who have similar interests and enjoy the same activities, possibly comparable education among other things, all in hopes of not having to go through life alone. If you have ever sat alone at a restaurant while having dinner, you know exactly how it feels to be alone when it seems that everyone around you is a couple, which brings us to our next reason.
Have you ever noticed that seats at a restaurant are almost always in even numbers and the small, quaint, out of the way tables have two chairs? This world is set up to accommodate couples. Just as the old song tells about a “bicycle built for two” many other things are as well. A love seat sofa would probably named differently if men and women had no need of one another.
