Can't send mail to that realm 2019

A reference to the popular TV show "Westworld"!

In the 2019 season of Westworld, the phrase "Can't send mail to that realm" is a recurring theme. It's a cryptic message that appears on screens and is spoken by characters, hinting at the idea that there are certain boundaries or limitations that cannot be crossed.

Without giving away too many spoilers, the phrase is often associated with the concept of "the door" or "the portal" that separates the world of Westworld from the "real world" outside. It suggests that there are certain events or actions that cannot be communicated or transmitted between these two realms.

The phrase has become a sort of meme among fans of the show, symbolizing the mysterious and often unsettling nature of the series.
