The funny thing is that for example and that example i'm going to use, you might also see it or experience, let's say when your talking to a friend, and were talking about a trouble someone caused you and while you were explaining it a random person who over-heard you got into the conversation to and started complaining without even knowing what or WHOM you were talking about :-/.
Twain might have used this because that's how some people are and the impact is that sometimes before you or anyone to be exact don't jump into conclusions or interrupt someone when there talking unless they want you to speak to them.
