Please help me with this:

Which line from the text best supports that the narrator has learned something about herself from her trip?

"I was so distracted when we got back to the hotel that I forgot to even ask about my bag."

"When I finally finished rattling off my plans, I realized that I hadn’t spotted my suitcase."

"I had accessorized every outfit and placed each one in the suitcase so that I could retrieve it as an entire, ready-to-wear ensemble."

"We later realized we had been in the Montparnasse neighborhood at this point, heading in the wrong direction."
