I have cities, but no houses. I have rivers, but no water. I have forests, but no trees. I have roads, but no cars.

I am not alive, yet I grow. I do not breathe, yet I need air. I do not drink, yet I die with water. I have no mouth, yet I can roar. I have no legs, yet I can run. Feed me and I grow stronger. Smother me and I disappear.

I'm not a plumber but I often hold a wrench. I'm not an architect but I often hold a measuring tape. I'm not a mechanic but I often hold sockets. I'm not an electrician but I often hold screwdrivers. In fact, I'm forever unemployed, but you'll still find me holding a hammer, pliers, bolts, nuts, nails, a drill, and more.

Crescent, no moon. Mechanical boon. An extension of hand, when connections won’t move. Assists with the crazy, while spinning in groove. While a monkey does loom, pipes are broken and doomed.

In the lungs I lie, Silent and slick, Guard by nature, Cast out when thick.
