Show, don't tell

So, Equestria Daily (a FiM fandom site) has what they call The Editor's Omnibus for fanfiction authors submitting to their site. In this Omnibus is a section called Show vs. Tell. In this section is the first time I've seen someone actually explain what that old adage means.

Show, don't tell.

The Omnibus sets a small scene for us, and gives an example of telling and an example of showing. Guess which example is vastly superior? The showing, of course. And as I said, this is the first time I've seen the "show, don't tell" principle actually explained. It was very eye-opening for me.
