Some facts about existing as a human: 

• Humans have always been weird.
• You are not the only human in the history of humans to do that strange specific thing you thought was just a "you" thing.
• Humans love to document the passage of time and their place within it. Example: Pompeii is covered in the same graffiti content as downtown Seattle.
• Humans have three consistencies across all cultures: craft the sharp pointy, share the much foods, and pet the fuzzy animal.
