When you think of the word, “rely”, what comes to mind? 
Now how do you convey that using everyday physical objects? I thought of “rely” in the sense of support. Whether that be houses relying on their foundations to stay standing, or people relying on other people for support.  I took these two definitions and combined them to come up with a house of cards. Theyeach rely on each other for support to make the word, whilethe entire house also relies on the foundation.
