When words are letters, and letters only

Words mean a lot to us human.
They can build up our sentences,
but they can also break them down.
Words can be so powerful,
but also so helpless.

Sometimes, they just don't mean anything at all.

If we're happy,
our words are happy.
If we're sad,
so are they.
If we're angry,
our words are angry.

But sometimes, they just don't mean anything at all.

Can we use
our words correctly?
Can we help
people through their lives?
Can we use
them to serve each other?

Then sometimes, they could mean more than we'll ever know!
