Actions speak louder than words.

It is our common experience to hear politicians make tall promise before elections, and to conveniently forget them after they are elected. Their actions do not match their words. That is why we do not trust them.
Words sound good. But actions prove the genuineness of one intentions. In olden times a man’s word was a matter of honour, even unto the point of death.
In modern times, people make all kinds of big promises which they have little intention of keeping. People like to say nice thing to give a good impression of themselves. But once they have left the place they think nothing of what they claim to do. We can only call such person a cheater or a liar. A person who says one thing and does something to the contrary is a highly irresponsible person, and ought not to be trusted.
We too should develop the habit of matching our actions with words at all times
