How to get an actor to follow another actor.

Ok so I am making a scenario where a floating boss constantly follows you. In the human-controlled class I have: 
    public int grumpyX = getX();
    public int grumpyY = getY();
and in the boss class I have: 
turnTowards(GrumpyFace.grumpyX, GrumpyFace.grumpyY);
The error I keep getting says non-static variable cannot be reference from a static context Can anyone tell me what my problem is?

The problem is that your values are stored in the object created from the GrumpyFace class, not in the class itself. So, you cannot get the values by using the class name; you need a reference to the GrumpyFace object. Once you get that, you will find that you do not need fields to hold the x and y coordinates of the actor; you can get them directly from the object referenced. 
GrumpyFace grumpy = /* obtain reference */;
turnTowards(grumpy.getX(), grumpy.getY());
The GrumpyFace object reference should be obtainable with this: 
grumpy = (GrumpyFace)getWorld().getObjects(GrumpyFace.class).get(0);
