Every day thousands of solipists die, their non-breaths witnessed by their loved ones after their last breaths the final refutation of their philosophy. It’s interesting that philosophy and neurological disorders like narcissism sit so closely when it comes to how you see the world. But I guess the main deviation is in how you treat people. One world view is thinking that the universe only exists because of you, and the other is believing it definitely SHOULD, and when it seems to not as it sometimes is then something’s wrong.
If this comic was made for only your enjoyment and yours alone, then maybe before your memories invert themselves into an infinity of non-breaths make sure all the people that you made up around you know that you actually think they’re pretty cool.
