a memory, from childhood, a real memory

do either of you remember
that day
when, pointed, we found
those flat glass blue beads,
buried in mud
beside the driveway;
surrounded by grass that
sometimes
a wooden fence
swung over
'cuz men riding
lawn mowers
glided past?
we found flat glass blue beads
as if they'd been there
for i don't know.
do either of you know
how they got there?
was it grandma pat?
was it papa?
