Mind the gap.

The spatial gap between the door and the platform at a train station is critical. If it didn’t exist, each train entering the station would screech with an unbearably high-pitched sound. No human would be able to tolerate it. While the phrase, “mind the gap” is a warning, it is also a statement of permission. The patron has permission to take a bigger step, to notice what’s below, and to avoid danger.

What gap exists for your good? Notice it. Avoid danger. Take a bigger step.
