The haven't been happening

The haven't been happening came
to the other day. It wasn't a normal.
First we all looked, then
it seemed as though we were going to have to.
But there would be a soon, very hopefully
to deal with. Later, the party
and all we were. Nobody could have!

Without the second, it was going to have
to wait a minute. Fortunately, though
- we suddenly have.

Never again could anyone ever, not
after such a sense we had - tremendous,
in those days. Why, it's a marvel no one's
made a name of it. What could it be then?

What could it mean?

Only such things
as have always fallen
together, haply by accident,
as if fate's chance
had finally come.
Would you?
