We communicate through tubes

We communicate through tubes: 

he has his, and I have mine.

And oriented properly - 

so that the ends would be touching

if only they weren't so far apart - 

we can not only see

but hear each other:

he in his world, me in mine.

And if I want to give him something,

I need only pass it through the tubes.

And similarly I can receive:

something from him as he from me.

And all this works through glass so clear

it is as if we're both right here;

but if our tubes come misaligned

I flee from his world, he from mine.
