Poem: Wall with a Tiny Door

Look at this wall, so strong I’ve built

Made to withstand every storm.

Smart was I, for I put in a door

A tiny door just for me.

Open or close, upon my command

This door only I can see.

This Dam of mine understands the rules:

• Open when threat of flood

• Open when fresh air needed

• Open when safety assured

• Otherwise, remain closed.
