Because

Boredom is a plague.
Boredom is a disease.
Boredom is contagious.
It latches onto the most vulnerable of us.
The ones who spend nights alone.
The ones who's minds are already riddled with depression.
The ones who can't escape, and have no desire to.
The worst side effect of boredom is that once you have it, you relish in it.
You spend nights alone, with nothing to do and no reason to attempt anything more.
Boredom is an ever growing problem in this day and age.
We've all lost loved ones to this epidemic, and will all lose more.
Just be careful, and don't lose yourself.
