After a week of multiple training sessions, I was exhausted. I returned my car rental and arrived at the airport five hours early to relax before a red eye flight home. Being a seasoned traveler, I watched the Transportation Security Administration (TSA) lines to decide which one to move into. The line I was in came to halt, so when I saw a gap in the line next to me, I took the opportunity to move over (for non-seasoned travelers, you can switch lines if you’re not cutting people off). Then, from behind me: “Really?” I didn’t realize the voice was talking to me until it was next to my ear, louder and more agitated. “Really?!” It was the woman behind me, a stranger.
