'Everything You've Ever Lost'

I heard a ring on my doorbell today. I answered it without a delay. I opened it up just part of the way. Then quickly peeked out, expecting to say. Hey! I soon realized that no one was there. I was just talking into pure thin air. I noticed a box that was shiny and square. From where it came, I was not aware. Beware! I lifted it up, and the address was me. I untied the bow with no guarantee. I opened the lid, and what did I see? Things that I lost, this sure could not be. Glee! I searched all around inside of the box. I found all these pairs of unmatching socks. I dug out a bag of childhood blocks. Even a key, not sure what it locks. Unlocks! I looked all around for that one special thing. I knew if I found it, a song I would sing. I know when I'll see it because of the bling. Please let me find my grandmother's ring. Shining! I hunted and hunted, then hunted some more. I had a great feeling I could not ignore. I knew I was close to what I looked for. Inside of the box left at my front door. Score!
