What is Love? (reference completely intended)

Emotions are fickle. This is what everyone will tell you in some way, shape, or form if you ask them why you feel a certain way about something when you legitimately don't know. Sometimes you might feel hatred toward someone you just met for no apparent reason, or you might feel really happy at seeing the color magenta and you don't know why. While all of these emotional responses are seemingly random, there is one emotion that is most definitely not random that we also still don't have a definite answer as to why we feel it: Love.
When it comes to the emotion of love, science gives us the basic reason: we have it because it is our natural instinct as humans to want to reproduce so we can continue to exist on Earth. However, this doesn't really solve the question of why love exists, since you didn't have to love someone to reproduce back in the stone age. With science and informal literature practically out of the question because of this, we can really only turn to friends and family to find out what love truly is besides just an emotion. Interviewing people, however, gives varied responses. Some people will say love is a beautiful emotion of attraction which helps a person find their true companion that everyone needs to have in order to survive and stay sane. This point of view is reflected by many people in the United States and is relatively custom to be followed by a marriage of some sort once the pairing has happened. However, several other people speculate the love is nothing more than a chemical reaction that is worthless in the long run since all it does is lead to great pain and suffering when a person that one loves leaves their life forever, either through normal departure or death.
In all, the concept of love is entirely up to personal speculation, which can make it really hard for logic-minded people who are lacking in social skills. My personal advice to them is to have them do their research on sociability and find what kind of people best fit their interests. then they can find someone who they can truly enjoy and, quite possibly, fall in love with.
