Can anyone explain usage of weak references?

The documentation doesn't explain it precisely, it just says that the GC can destroy the object linked to via a weak reference at any time. Then what's the point of having an object that can disappear at any time? What if I need to use it right after it disappeared?

Can you please explain them with some good examples?

Thanks, Boda Cydo.
