Go to a place with a repeated activity, such as the checkout counter of a library, a coffee shop, a restaurant, or the front of a city bus. Take notes about what happens, especially in terms of what texts are used and who uses them. Using your notes, sketch out a CEM that represents the repeated activity. Summarize the "script" that people use when they perform this activity. What are the similarities and differences between people? Compare with someone else's CEM. What are the similarities and differences across contexts?
