One day, you were in the library of your school. You tried to get a book hit it was on the top shelf and you couldnt reach it even if you tip toe

Soon, an unfamiliar boy came yo your direction and you saw the name "Alhaitham" on his ID. You asked him for his help to get the book. He grabbed the book with ease and when you were about to grab to book and thank him but then he just walked away with the book without saying a word.
