A time when one was two and two was one

Recall the old days when one made two,
and two made one in the past of the two,
those old days in which people thought of pairs,
the old pairs that formed a one in a group of stairs,

Stairs that were reaching for the sky in union,
on the past where we tried to reach in unison,
just like the current of a river that hold all together,
back when two made one, one who looked for an answer.

Yet I wonder, what happened with the one who looked,
the one who looked and in the end disbanded,
and from one it became two, two who got lost,
one who became two, and two who walk without the other.

Like a pair of stars that goes without crossing the other path,
the two who were one are now two, and I can't avoid to think on their aftermath...

Can the two become one again? Or forever shall they keep being one,
getting together with other who won't make a one, but just two beings,
for the two who were one, can't be one without the other one...
that one who has gone lost just like the other...
