Last year, I planned a trip to another country. I packed my bag and went to the airport. At the check-in counter, the woman said, “Passport, please.” I looked in my bag—but it wasn’t there! I forgot it at home! I felt shocked and said, “I’ll go get it.” I called my brother, and he brought it in 30 minutes. I was lucky. I checked in just in time. I learned a big lesson: always double-check important documents. Now I make a list before every trip, and my passport is the first thing I pack.
