There is much spoken about emotions, one should not be afraid to display them but they should not be worn upon your sleeve so I’m guessing display around the torso is best? Emotions are perhaps the most difficult of human interactions since they often carry huge investment yet they are invisible to all but the owner.
For me all emotions are two way streets, they all require some other person to feed off after all there can not be an emotion without a target. Love, for example, needs another human as a target, as the loved and as the principle which maintains the state. Hatred, whilst a wasted emotion, must be directed at another to find its potency, I firmly believe that hatred only serves to feed that which it is directed against but without that target what would you hate?
This goes on through the whole tumult of emotions, without a loss how could you mourn? If there was no other then what could you be jealous of? The emotion of regret is however the most selfish of states, when one regrets then they do a disservice to the other party in the partnership which is cruel beyond that which is regretted. A mistake made and regretted in a relationship for example is not the same as sorrow or mourning it is, in its true essence, an emotion focused on that which you have taken away and not that which you have lost.
It is important that we learn from mistakes and bad choices, that we take these lessons with us on our journey and that we are become wise enough not to repeat our errors, or at least those particular errors. I don’t believe we should regret, after all one can only reasonably regret that which one influenced and rarely, if ever, is that the sole recipient of the loss. So let us allow those that have lost the bitter luxury of sorrow those that have created the loss deserve no such respite.
