Problem: In a well-developed, well-organized paragraph, take about a ritual within your own culture from an outsider's perspective. Try to envision the activities and customs as though you are witnessing the practice for the first time and trying to wrap your head around their significance to the "local" culture. Be imaginative, but keep it simple. Preparing for a prom, try-outs for a team or theatre group, doing yardwork, or preparing a special dish are but a few examples of everyday activities that could seem bizarre to someone not of your culture.
ALTERNATELY, you may choose a behaviour/custom/trend in the United States that you think is foolish or faulty. Remember that you are narrating as though you are an outsider looking in at and describing an activity that is strange to them.
