The wall is really talking

A simile or a figure of speech that represents how a very quiet and careless person will give in and understand how to recognize the feelings of others.
This figure of speech also derives from another simile of the phrase, "It's like talking to a wall", which means that someone may act so careless and helpless that they won't saying anything to help others.

Finally! Someone understands me! For once, the wall is really talking.
