No. The definition of chatter is below my post. Even used as a noun, it cannot be a person. But I know what you mean. If there is a body next to me, I will talk to them.
And just in case you didn't notice, I'm a stickler for correct grammar and spelling. Lord love a duck, I don't know why I'm this way.
