+Follow the rules to avoid/fix notGCed and notDisosed leaks:
 
 1. **Ownership**. Every disposable object should have clear owner that manages its lifecycle.
 2. **Disposal**. The owner should dispose the disposable.
 3. **Release**. The owner should release all links to the disposed object (unless disposal happens
    in owner's `dispose`, because in this case links to the owner should be released and
    thus enable garbage collection).
-4. **Weak referencing**. Not owners should either store WeakReference for the object, or make sure to
-   release the references becore owner disposed the objec.
+4. **Weak referencing**. Non-owners should either link the object with WeakReference, or make sure to

 If you see notGCed leaks, where the retaining path starts with a global or static variable,
 this means that some objects were disposed, but references to them were never released.

+In this example, as `disposedC` is not needed anymore, it should stop being referenced when disposed.
 If `A` and `B` are still needed, `B` should assign null to the variable that references `disposedD`.
 Otherwise, the reference to the first non-needed object on the path (`staticX`, `A` or `B`) should be released.
 
 ```

-To fix the leaks, you need to release closest to the root object on retaining path
