Describe a place that you associate with your childhood. It could be your room or another room in a house, or a place that you used to visit as a child, any place that reminds you of what it was like when you were a kid. It might be a positive place that reminds you of what you liked about your childhood or a negative place that makes you glad you are rid of it.
Think about the words we use to describe a place in order to explain the vibe that we get from it. Word choice seems important here – ask yourself why you are choosing a certain word and what feeling that word, as opposed to other similar words, will give the reader. Consider the different sights, sounds, smells, feelings, and emotions that you associate with this place to give the reader a real feel for what it was like to be in this place. Your goal is to transport the reader to this place that you associate with your childhood and make them share your experience of it.
