The observer/speaker is usually hidden in any statement we make. Take the following statement:

There are things.

While the speaker is pointing out objects in space, the use of ‘there’ hides the fact that the speaker is ‘here’ observing the objects that are ‘there’. In other words, there are not only the things observed but also the observer/speaker as a thing as well, only it is made invisible by the form of the statement.

Admiringly, it is difficult to avoid, for this is the characteristic of language. So it is imperative that we point this out, be aware of this fact of language that is not a fact of reality.

Every statement, whether this fact is hidden or not, includes the speaker and the listener.
