Throughout our lives we experience countless relationships with others, from our parents, siblings, children and families to those we work with, play sport with and meet as fleeting acquaintances. Every relationship we have has an influence on who we are as a person, from the briefest of encounters to the longest of partnerships. We experience feelings and emotions from all those we meet and engage with. Relationships are a choice (such as the selection of a partner, lover and spouse), all begin either through a genetic connection or from a chance encounter. What draws us to one another?
