wee small voice
small voice
voice of conscience

You can still back out, a small voice inside him said.

But a small voice kept her from running to the phone.

But then a small voice had started to say, in the back of her mind, Are they really?

Far back in his mind, a small voice told him this was what he got.

But a still small voice within me says there might be something in what you say.

I thought back to that still small voice inside me.

A small voice in the back of his head told him to hope someone there could still give help.

And then came a still small voice, which asked him what he was doing there.

A small voice in the back of his head told him he could do it himself.

It makes no sense, a small voice said in the back of her head.
