Michelle K's poem describes what it feels like to change yourself in the hope of being kept by someone. The speaker pictures a person folding themselves up like paper, pressing the creases sharp, so they can slip into the cracks of another person's heart. It's a painful image: love here means making yourself smaller and more awkward, not feeling welcome as you are.
The language of prayer ("holy," "praying") shows how desperate this hope is. The person stays and waits, believing that if they hang on long enough, he will hold them together. Then the tone shifts. The speaker admits the hope is "dangerous" and speaks directly to the reader as "Darling," almost like a gentle warning from someone who has been there. The closing line, "people are not glue," is blunt and simple. The mood is tender but sad, with a quiet note of hard-won wisdom: nobody else can repair what is broken inside you.
