Usually, this conversation ends with them not believing me, and me thinking maybe it's time to stop trying to talk people into this concept.
Today, that all changes! I have proof to back my reasoning! I am going to show you what my artwork looked like when I was 7 years old. For some sadistic reason my mother recently framed this and hung it in her home, where I can now see it on a daily basis:

Yes. Happy Faher's Day. (See inscription in the clouds.)
This was the best I could come up with before I had training or lessons of any kind, and my 7-year-old self thought it was pretty kick-ass. For some added fun, try figuring out what this painting is actually OF, and then click on the picture below for some startling revelations.
