I think "screen failure" usually means a broken screen.
Quote:
This princess lives in a glass castle, that princess on a glass hill; this one sees all things in a mirror; they may all live in glass houses if they will not throw stones. For this thin glitter of glass everywhere is the expression of the fact that the happiness is bright but brittle, like the substance most easily smashed by a housemaid or a cat. ...
Remember, however, that to be breakable is not the same as to be perishable. Strike a glass, and it will not endure an instant; simply do not strike it, and it will endure a thousand years.
