Asteroid Collision

It rocked my world

when I lost that game of marbles.
My shooter was a brown agate.

I’d start the day with just a few
and go home with my pockets full
(but it rocked my world

when I learned you had to shoot
from the edge of the circle).
My brown-agate

shooter could be a dead-eye;
and there was a technique
when you knocked out a rock

of making your shooter stop and spin,
and then you could keep on shooting;
but you had to make sure your precious

shooter and the last marble left the ring
at the same time or your mib was game.
My world got rocked.
My shooter was a brown agate.
