Grumbles

Do you have Grumbles in your town?
Where I live they are all around.
At the house and the playground,
you don’t see them but they make sounds.
You find them at the store or on the bus,
where folks gather to discuss.
A Grumble might like to moan,
or mumble in a lowish tone.
Some Grumbles are louder sorts,
you can hear them gather at team sports.
Some Grumbles, they might sigh,
or whine and bellow and seem to cry.
Grumbles are a part of life,
they make their noise but cause little strife.
If you meet a Grumble in your day,
he will want to have his say,
but once done, he will go away.
