Memom

Thank you for my bones I use my flesh that you once gave me but we are two creatures that share too much with our backs touching one another I live with you can cannot live without you but sometimes only without me I feel you can live and when I am a small again in the hugeness of your oubliette eyes then I can only see that your creation cups me like the gentle hands of a bird wanting to fly free If you cup me maybe I won't fly away You do anything for me but

Name one thing I've done for you
