It was ocurred in the last final school trip. All students had been met at the airport by the head teacher.

Adam arrived at the airport 30 minutes late. He brought with him a big luggege with him. He never broke away from his bag. Also, when a teacher helped him with his suitcase, Adan began to be very nervous.

Just before getting in the plane, Adam's mobile rang. Then, cut off his mobile and he came back to his house.

Maybe if his mobile hadn't rung or he hadn't brought that strange suitcase with him, he could have travelled with us, I don't know. He told me that he regreted not getting in the plane.
