Postcard

There is a house in the picture 
Inside the house is a room 
Once round it is a short circuit 

When times are hard I think about you 
Four walls, one has a window 
One has a door, which I go out of 
I just thought you'd like to know 

I don't think you're listening 
I think I'll tell you again 

This clock shows only mythical hours 
These books show only fictional days 
One system is only as good as another 

I don't think you're listening 
I think I'll tell you again 
I just thought you'd like to know
