Forgotten Yesterdays

I breathed argon and oxygen I dove so deep,
          I climbed until the sky turned black,
With air, so thin I could not see, but questioned still,
          I grew weary of their questions.
Asked a dozen times, in as many ways,
          Yet no one would listen to what I had to say.
So now I've turned my, back,
           and walked away.
Each day the sun still comes up,
           maybe it still shines,
                       on my friend Michael today.
