On the way back to his home, Amr met an old man seeking his help in searching for a specific address for him, but Amr went far away from him!
At the entrance to his house, he encountered his neighbor, Mrs. Sa`ad, going down the ladder, but her foot suddenly slipped and she fell down. Of course, she thought that Amr would give her a hand and help her, but he looked at her carelessly, and then went up on the ladder quietly!
What is Amr up to today?!
What is this change that has happened to him ?!
