You and your friend barely sit down when the blood-curdling screams start. You rush out to see who's hurt, only to find your two children, each determinedly tugging on one arm of a doll, screaming.
It's a scene that plays itself out in thousands of homes every single day, but that does not stop parents from feeling frustrated and embarrassed.
Being charitable is a sophisticated skill. It's not something that comes naturally to a small child, but with your support and encouragement, he'll eventually start sharing like a boss.
