The three most common biological relationships; mutualistic, commensual, and parasitic. A mutualistic relationship is one that benefits both sides of the party. A commensal relationship is a neutral relationship, where it doesn’t benefit, nor harm you and the other person. A parasitic realtionship creates harm, and is only beneficial to the ‘parasite’.

In my life, one example of a mutualistic relationship is one that I share with my daughter. We thrive together, myself giving her love and care and getting the same in return. Our relationship is beneficial to the both of us.

An example of a commensal relationship in my life are the many people in my classrooms everyday. I don’t mind any of them, they don’t mind me, so it is very neutral. In my previous relationship, both of us were parasites in different ways which caused a great deal of harm and our seperation.

In our lives, many relationships come and go with time. It is important to keep those mutualistic bonds, because they are the most beneficial to our well-being and happiness.
