Spend time in a public place where its easy to find ppl and make careful observation of ppl interacting with others. its important that your prsence doesnt doesnt affect their behavior of those you observing.Compile and intepret your observations in terms of social psych thoery (mostly social perception and self presentation).Be sure to include only the observation that you can link to social psych in your paper. Finally you must interpret your own observation from a social perception perspective.
