This is a memory recall exercise from Lynda Barry, variations of which are found in many of her books (Syllabus is a great place to start). Choose an image or object—LB uses “cars,” and “other people’s mothers” as examples. Make a quick list of ten instances in your own life of that thing. Choose one of them to focus on, preferably one that sprung to mind as you made your list—LB always encourages us to go after anything that surfaces without overdetermination on our part.
Draw a big X across a whole page. Visualize yourself in the presence of your chosen object so that it’s a scene in your mind. (If you chose, for example, your best friend’s car, visualize yourself in it on a particular day in a particular place instead of all the times you were ever in that car.)
On your X-page, with a 4-minute timer going, record sensory, present-tense details of the scene. You can either write indiscriminately across the page, ignoring the X, or you can use the quadrants the X provides to locate you in space, so that you record what is ahead, to the sides, and behind you, as if you are positioned at the intersection of the two lines.
Then set a timer for 7 minutes and, on a fresh page, write a description of the scene in the present tense.
