Lock

I can buy a lock.
I can take one off a shelf, out of a store, 
And then shut away anything I choose.
I can keep the whole world out of my room.
The universe couldn’t infiltrate a cupboard
If I willed it so
With my lock.
And yet,
There is always someone able to get in.
Someone with the loophole, not the key.
A stick of dynamite, a wrench. 
A key of their own, that just so happens to fit. 
A key I gave them, once. 
Until I learn to forge my own locks,
With all the chains and seals
To stump loopholes
Or thwart keys,
I am a little bit
Open.
And if forging my own locks
Still cannot keep the ghost upstairs from
Floating down any corridor he pleases,
Then what need have I for keys or loopholes
Or locks at all?
