Delete

It's so easy to delete pictures, or throw away sentimental objects, or give back letters, or block communication.  But why isn't it so simple to delete memories that plague one's present?  The ones that manage to hijack any train of thought, break into any mental safe that you try to secure your thoughts with, and rob you of your joy, focus, concentration, and motivation.  If you're going to leave, why don't you take everything with you?  Why do you leave traces behind you?  Like the tip of a blade that breaks off and starts digging its way toward one's heart even after the knife is wrenched out from the wound made where it was plunged.
