Action Speaks Louder Than Words, What Does The Saying Mean?

Allow me to offer two examples:

1) We are sitting in a restaurant eating lunch.  I say "this is terrible" and continue eating.

2) We are sitting in a restaurant eating lunch.  I show a disgusted look on my face, throw the plate on the floor, and leave the building.

As you can see from example 2 I used no words but my actions speak for themselves wouldn't you agree?

This saying is pointing out that while people may say one thing, their actions may be saying something quite different, and it is their actions which give the better indication of the person's true nature.

Simply put: You can say you agree with something. You can say you are figting for a certain cause, but until someone see's you physically "fighting" for / standing up for that cause, they might not believe you.
Or another one: You can say you love a person, but when that person is in need, your help will show them that you love them.
Words do not always mean anything.....it is what you do that makes you what people look up to
