To lock the world out. Bolt the doors, monitor the security videos. Be safe inside a fortress.
Let in only the most trusted of the trusted, those who've been tested and proven, who'll never lie, or deliberately be hurtful. And you'll know that they'll do what they promise, and when they are hurtful it's an accident.
Where safety matters more than sunlight, and security more than rain.
