Nor should you be defined! You are you. You are unique. Wise Dr. Zeuss put it best. "No one is youer than you." I suppose many of us lament the change in our physical appearances as we age. I believe we see ourselves as perpetually young and are shocked when the mirror image disagrees with us. Yes, be complex. "Some people make me prickly." You and me both! We are human. I have but one suggestion. Use quotation marks " around "you're old." Thanks for the read! This is a great poem.
