You

Sometimes you are the wrist.
Someimes you are the blade.

Sometimes you are the spider.
Soemtimes you are the web.

Sometimes you are the sun.
Sometimes you are the shadow.

Sometimes you are the tear.
Sometimes you are the stitch.

Sometimes you are the ink.
Sometimes you are the words.

Sometimes you are the lock.
Sometimes you are the key.

Sometimes you are the wound.
Sometimes you are the healing.

Sometimes you are me.
Sometimes you are someone else.
