enumerated lengths of tile
in the second-floor hallway
contained all our days for a moment
a capsule spilled open
there were still doors for
97 students
16 teachers
now I don't know any of them
shadows filled and merged
low black clouds
in a crack of still-lit sky
when noticed, vanish
in an after-hours classroom
using an off-limits computer
a clock in the corner of the screen
messaging a friend I can't remember
the sound of a door shutting firmly
when they eventually logged off
who have you forgotten?
a chalkboard erased
dissolved and dispersed
one cloud reversing
