You can really understand how bright the moon is if you're in a place that's dark without lights,only relying on the night skys brightness.
You can really understand something when its the point of focus
Just like in the case of the moon,when you're surrounded by lights you see the moon as a tiny point of light in the sky,
But when the lights go out,you realise the moon actually illuminates.
In a dark situation,a seemingly little thing you didn't ever picture making sense,actually would make sense.
Like the bible you might have left dusty on the shelf,
Or even someone you never thought you'd ever befriend.
