Marbles On The Mantel

There are marbles on the mantel
in a bright blue crystal jar
I store them there in case i loose one
and it rolls away to far
Sometimes my life's confusing
and my mind may not see clear;
although this has not happen
to me in many years
Yes those are the replacements
for the ones inside my mind
If one should ever fall out
I can replace it just in time
Please do not touch my marbles
or they may accidentally fall

Someday I may have to replace them all
