I Do Not Wish to be Part of this Enclosure

A puzzle:
Two ends of string
Attached, but not really
Not physically, anyway
I pull them apart
I bring them together
They hiss
They spark
They hiss
They spark
But their purpose
Is still unclear
I stop and stare
I hmmm and wiggle the string
It's indifferent either way
I tie the ends together
Creating an oroborus
Which turns into a snake
Bites me
It won't let go
Coiling around me
Until I and the two ends are one
Either end attached physically
By my very presence
It is hard to tell which is me
Which is string
So endlessly tangled are we
Into the same entity
The string must end one place
I must begin another:
A new puzzle.
