Relationships are all about how we connect with each other. When this connection is at the level of conscience, it is a very deep connection and even without physical presence, this connection remains the same.
Most of the relationships need physical presence because that’s how most of the people connect with each other. People get so used to having a physical company that their emotions are attached only to the bodily presence. When this company is missing, their mind begins to look for support somewhere else and slowly their emotions for the distant relationship start to fade away.
Connect with people at the deeper level, you will feel them even in their absence. It does take a deep relationship and a strong mind to stop your emotions from wandering around.
