I have a granddaughter who is a junior in high school. Recently, she needed to write a report for her history class on any subject related to a federal government program. Because she knew that her grandpa worked for the Social Security Administration (SSA) for 32 years, she initially thought she'd write about the history of Social Security. I told her that was actually a pretty broad topic. Many entire books have been written about that subject—and her paper was supposed to be limited to 1,000 words.
So I suggested that she concentrate on the history of just one small part of Social Security, something her teacher and every student in her class were familiar with—the Social Security number (SSN). After all, everyone has one.
