Break me again

It seemed so real when you were here Like a flash you disappeared All the memories I had to clear Those empty champagne glasses with no one to cheer That time I knew I had no one near It felt like years but I shed no tears Your absence gave me strength So, I built up a wall for my defense Made you sit up on a fence And retained it for suspense I think I know why I couldn't feel anything Those cuts took time to heal Hope now you can see my nerves of steel Would love to see you break my shield
