Children, once they're grown

Children, once they're grown

Children, once they're grown,
are gone forever.
Where do they go to?
Why does time never stop?

Sounds like the typical parental whine, wondering why you would open with this, feel I'm missing something.

Why can't it be like how they
told us of the future
in comic book shops - 
where the past is a page we could visit once again,
not in the mind, as through a window pane,
but walk in once again?

I'm almost with you here, but then, for me, rereading a comic book is like looking through a window pane, it doesn't come alive to me the way it does to your N.

In Browning's retold rhyme
the piper wasn't death, only the 
passage of time.

Oh, the piper, my childhood crush, I wanted to join those children. So for me just saying The piper would be enough, but maybe he needs the intro. Either way, I think you could do something interesting here that leads the reader to your conclusion on their own.

Tell me there's a way 
to come back from tomorrow.
Time is at the quantum level
a double headed arrow,
merely an illusion, pure poppycock.

I like the first two lines here, trying to like L3, love the double arrow, I can see time traveling from each end. But I don't think that's the illusion you're leading me to. I'm confused.

So can you turn back the clock 
to just my boy and me?

I don't know enough about these two to understand why the now is unacceptable.

So, I haven't been reading too much poetry lately, before the last few weeks, so apologies if there's something I'm missing. I've been trying but I just don't get the tone of it. Thanks for posting it so I could at least try.
