Saying something is “obvious” without specifying an audience is meaningless.

(because obviousness is subjective and depends on the knowledge, experience, and context of the audience)

Notice the “IMO pretty” before the word “obvious”

IMO means “in my opinion.” I used that phrase to express how the following statement is my opinion and not a universal truth. My “audience” in this case is myself.

I do that because otherwise there’s always a comment saying how things like “obvious” can be subjective.

I also used the word “pretty” to, again, soften the word “obvious” so that readers don’t think that it’s a universal truth.
