It stands to reason that the longer we are in relationship with another person, the more we can predict their behaviors and patterns. After many years together, a couple will have a shorthand with each other; finishing sentences and correctly interpreting an icy glare or a cheeky smirk from across the room. This inner knowing of your partner is a blessing and curse as many times it goes against another real truth about being human; that we are often unpredictable, always complex and ever-evolving creatures.
