Take yourself on a field trip to a place where there are other people. While you are there, collect details that you can write about later. Try to notice details that appeal to all of your senses.
Here’s the catch: Don’t collect any details about the people.
Instead of an actual, physical field trip, you can go on a field trip in your imagination. Do this by traveling in memory. Or do this by making things up.
When you have filled a page, give your work a title and write the date on it.
