Tip of the Blade

I give you,
My friend, my ally,
I give you my trust,

I lean on you when I am weak,
I ask you for wisdom,
I turn to you for help,

But what happened?
Suddenly,
I felt the tip of the blade creep into my back

What changed?
What did I do to deserve such betrayal?
What turned us on each other?

I gave you,
My friend, my ally
I gave you my trust.
