Years & years passed & the couple had 5 children, the first ones were boys & the 5th was a little girl. When she was born the father was extremely happy that Almighty blessed him with her, and he threw a huge party for her in grand style. People were so amazed with his joy and happiness that they asked him, why are you so happy with her more than you were before with her older brothers?
He answered simply: “She is the one who will open the door for me.”   (Author unknown)
