Fatal Flaw, a poem

My fatal flaw
Ain't against the law,
Even though people
Disappear.

Quick and clean
A well-oiled machine
It leaves no
Trace of blood.

I stop communicating
There's no hesitating
Another friendship has ended.

The reason's always the same
The friend is never to blame.
I simply lose interest.

I need
To be challenged
Proximity
Common interests
A bonding experience

And sometimes
Even those aren't enough.
It's tough
To change one's nature.

In the end
Will I have a friend?
Perhaps I won't
And I doubt it will matter.

When I need
Someone the most
I'll likely find only ghosts.

Whatever my fate
I can't overstate:
My nature prevailed.

Dying alone
No one to phone.
Thanks to 
My fatal flaw.
