Glass

Every morning she stood in front of the window waving.
I waved back, but didn't know who she was.
Outside life continued, but hers
didn't extend beyond the glass

When I came back from school I looked:
fourth window, ground floor:
a white wall stood silent
as if she didn't really exist.

Then I ran into her outside
her tread careful as if walking on broken glass.
She suddenly didn't knew who I was.
