I am with the ones saying you shouldn't "showcase" it too much. Basic manners there. I am also one of those that got about 3 birthday invitations throughout school days, was alone at all those parties and heard about many more in school, on lessons and on the breaks. It shapes kids in no good ways. Many throw around terms about things they do not know much about. "Git gud" doesn't help, sometimes education (of children and grownups, about manners) could be in it's place. I don't mind people talking about their happy meetings, I mind people excluding someone, the same every time, with the acceptance of parents and society. Kids aren't kindness incarnated, and if they aren't taught kindness, they will most likely not automatically acquire it until they're grown-ups either.
