If you want to fold a paper in three equal parts, you need to apply a Z-fold. If you want to fold a paper in four equal parts, you need to apply a gate-fold. If you want to fold a paper in five equal parts, you need to apply a stair fold. The name "stair fold" is given here since the final shape resembles a stair.
the quietness of the
setting sun is haunting
the hurried chirp of
the returning swallows
echoing round the school
evokes a forlorness this
evening chill works to thicken
those flighty years have
come back like swallows
to roost, each echoing
a pain, a joy, a tear, a
smile, a hug, a kiss, a loss
each step of this stair
spins a tale, walks me up
a time warp of yearnings
and disillusions
the stair where a thousand
dreams were spun and another
thousand trailed the wind
