She almost screamed — her smartphone was missing! Jane tried not to panic, although it was very difficult to stay calm and think clearly. She had all the important notes and contacts in her phone. All Jane could remember now was putting her phone into her bag before the plane landed.

Right at this moment Jane felt someone touch her shoulder. She turned around and saw the man who had been sitting next to her on the plane.

"I believe it's yours," he said while giving Jane her smartphone.

"Oh, it is! It is mine! Thank you so much!" she was super excited to see her phone.

As it turned out, the man found her phone in her seat after she had left the plane.

So after all Jane's trip was successful.
