This week, explore your backyard at night. Or, if you are able to, take a walk around a park after the sun sets. The world is different. It sounds different, it feels different - it even smells different. Quiet rustles in the grass sound louder. Different animals are out and about: bats, moths, and around here, coyotes.
Write down the things you notice at night. Then, if you have the opportunity, go back in the daytime and write down what you notice.
