Making the story sad:
... Jane got to the airport early in order to check in. She didn't have enough money for a trolley and her bags were too heavy, but she had no other option but to travel on foot up to the airport.
Hopefully, when she arrived, she found out that the flight was delayed for 2 hours so she was yet in time. When the flight was called, she boarded and took a window seat.
On board, almost everything was OK, let alone the itching of her back under the sweater, still she didn't even feel airsick.
However, when she left the plane, she felt that something was wrong, something was missing. She opened her mouth in a silent cry: her belongings! The purse, her big bag with her passport and ... suddenly she felt dizzy. It reeled before her eyes... Jane fainted.
What was missing? — It was her belongings, which were either stolen or forgotten on board.
Did she find it? — Not in the time of the narration; maybe.
Was her trip successful? — Every dog has its day.
