It is also possible to invoke the `Write` method by accessing this property with `w.Writer.Write()`. We are no longer receiving a panic and can now use the `NullWriter` as a `Writer`. This initialisation process is not much different from having properties which are initialised as `nil`, as discussed previously. Therefore, logically, we should try and handle them in a similar way. However, this is where embedded interfaces become a little difficult to work with. In a previous chapter, it was explained that the best way to handle potential `nil` values, was to make the property in question private and create a public *getter* method. This way, we could ensure that our property is, in fact, not `nil`. Unfortunately, this is simply not possible with embedded interfaces, as they are by nature, always public.
