Possessive Memories

Some memories want all of my time. As though I have nothing else to do. They want exclusivity, are unreasonably possessive. And often they are not the ones I want to have, to keep. They act as though they have free will over mine. I know I lack control. Have you ever tried to block out unwanted thoughts or memories? Right, no chance. So, it seems that their presence just has to be tolerated. Of course, where would I be, who would I be, without memories?
