What's So Great About a Fence?

Seriously,
it's been
confusing me.

Here,
they love them,
sometimes for
no reason,
and with signs
that have
no purpose.

My childhood
was splayed
by a fence;
it was a big deal,
then I think
they moved away,
leaving the fence.

So what happens
when something
like that
is left
and its
original purpose
gone?

Maybe
you could
tell me.

Make it
in small words,
so we both know,
or in big ones,
so someone
may be
amused.

Either way,
I just don't see
what's so great
about a fence.

I think
it just gets
in the way.

If you wanted
privacy,
theoretically
the building
already gives
that,
with its walls,
unless you have
glass walls
or like
to strut around
in the nude,
or play baseball.

But that
can be done
in the street.
