Poem - A World of Your Own

As I sit here across from you,
  Wondering what it is I did
    to have earned this regretful view,
  I realize, from me, what's been hid.

One is forced to accept,
    that the past will remain unchanged.
  Then, it's realized how one can be so inept,
    when the past's been mistakenly arranged.

One cannot, and won't, believe,
    that the future relies on bygone days.
  There's not much to do but grieve,
    when one realizes their errored ways.

While you sit in a world of your own,
    I'm stuck with my regretted sin.
  Had I been able, you'd have known,
    how happy we could've been.
