You can joke

But that doesn't make it funny

I might not cry

That doesn't mean I don't get upset

I may smile

That doesn't make me a happy person

Maybe I don't act out

That doesn't mean I'm content

I might write

But that doesn't flush out the darkness

I may think

But that doesn't make me smart

I can look

But that doesn't mean that I listen

I don't laugh

But that doesn't mean I have no heart.
