What can happen when turning a corner?

Do you know?
Today I met my double

We ran
into each other
when turning
a corner
no umbrella
in the rain

We look at us
for a second
with a point of fear
in our eyes

Was she me?
was I she?

but followed our way
may be scaping
from the same

Perhaps she was coming
from where I was going

Brief encounter without words
mirror that does not break
when crossing its sides like this
