I find that the energy of contact leaves residual traces of itself imbued within the objects of any particular interaction. Depending upon the intensity, charge, and duration of that interaction, determines the amount of trace energy and the contextual charge ( positive/negative) that is impressed upon said object of interaction. I find that I hold onto things that are of a positive charge and discard things that are of a negative one. The interaction that I have with those things periodically to this day reinforces the positive charge between us. The fact that you throw them away means that you were either indifferent or negative in charge relation. It is what it is. I suppose some sadistic self harming people might hold onto something that provides them with a negative charge but it is a reinforcing negative/ unhealthy practice)
