What may be a nightmare to the common eye
Can be essential for those that rely
Parasite wasp may find me essential
But I prefer to stay confidential
The world may say I’m a threat, I’m dangerous
And to that I would say outrageous
Some may say I will deprive
But I’m just trying to survive
Although I would come in touch warily
I like to think I’m useful in therapy
Whether for oncology or delivery
I claim it as chivalry
My name is damaged and cursed
They always think the worst
Yet I find myself to be mutualistic
Its not an opinion, but a statistic
I’m an unsung hero
Not a foe
It brings me sorrow
And all I can do is look through the narrow
What am I?
