Not sure whether to complain to the school but I have just seen an end of term play put on by the year 5's & 6's and there were scenes where the children were acting out being drunk with pretend glasses of wine, lewd conduct between a man/female scene (the woman who was married wanted to sleep with another man she found attractive and was making advances to him), and then there were scenes of stereotyping various nationalities in an exaggerated way - ie French wearing strings of garlic round their neck).
I know it's just a play and is hardly crime of the century, but it rankles with me that schools should be presenting a better moral example to such a young age group. I guess it's no different to acting out scenes of other drug taking or stereotyping races based on physical characteristics. I cant think of any benefit to encouraging young kids to act out such things and it wouldn't lessen the entertainment value of the play to leave them out.
And yes, play acting getting drunk wont necessarily lead to them becoming alcoholics, but I still think its better not to include such scenes.
Would you complain if you were me?
