We had neighbors living below us like that.  They would even come up and cuss out the kids when they thought they were being too loud.  That was carrying it a little TOO far.  My hubby let them know what he thought of that!
 
Well, we were in the process of having a home built and on the day we began packing we made sure to drop every pot and pan we had in the house!  ...among other things! 
I know that's mean, but it felt soooo good..
