An engg student had a crush on his classmate. One fine day he proposed her. But she rejected and threatened that she would complain to the principal if he ever bothered her again. And the boy remains silent for rest of the days.
Some days later the girl borrows a book from that boy and writes in it
.
.
" I love u too. Sorry to hurt you the other day. If you forgive me, please come and speak to me."
Four years passed, and the boy never approached the girl again.
MORAL: Engineering boys never open their book!
