angry at something

you're angry
at something,
or someone,
but you don't
know what
or who it is.
something's not right.
there is a bruise
on your soul
that you don't know
how it got there.
it's black
and blue, pulsing
as you sort backwards
through your day,
who you spoke,
or listened to.
it weakens you,
this anger,
makes you limp
down the street
with the others
who are limping too.
