It's like when you're driving on the road.
You're going one way,
and there's another driver coming the opposite way.
And at one point you stare across to the side
And they do the same.
And your eyes meet.
It's that stare,
that connection.
You don't know each other,
there are no words,
no feeling,
no acknowledgments.
Just in that moment,
an glancing exchange,
and then it's gone.
No retention of feeling,
it just happened.

It's like a wall.

No, with a wall, you cannot see anything.

A window, then.

I suppose yes...a car window. Seeing without.
