Passport Oath

As Cassie was getting ready for her vacation, she had always wanted to travel abroad. She had saved her money for several years and finally had enough for her dream vacation. Until now, she'd never even been out of the country (going to the Grand Canyon via Florida doesn't count), so naturally, she needed a passport. She went to the Passport Office and asked what she needed to do to get a passport.

"You must take the loyalty oath first," responded the passport clerk. "Raise your right hand, please."

Cassie raised her right hand.

"Do you swear to defend the Constitution of the United States against all its enemies, domestic or foreign?"

Cassie's face turned pale, and her voice trembled as she asked in a small voice,

"What.... all on my own?"
