When I was in primary school, we read a story about a little girl, who never liked to share her things with anybody, her friends and family inclusive. Whenever somebody touched anything she owns, she cried out, "it's mine, its mine", while every other person gladly let her share in what they have. One day, they all got tired of her attitude and decided to teach her a lesson. They agreed not to share their belongings with her, whenever she touched anything belonging to any one of them, they told her, ‘it’s mine, don't touch it". She cried so hard that day, thankfully she learnt her lesson.
