First of all I will lay all my cards on the table and confess that I do find the Dad I'm about to talk about a bit of a knob anyway so this may be clouding my judgement.
6 yo DS (along with most of his class it seems) has just joined a local boys football club -very popular and well run from what I can gather. On joining up the boys and parents are given the Codes of Conduct about the team spirit/support each other/do your best/behaviour expected/etc of all involved.
Anyway, last week during the course of the session a few of the boys made some bad moves (own goals, missing kicks, falling over type of things) which is perfectly normal for boys of this age surely but this Dad was of making a big thing pointing, laughing really loudly and making derogatory comments along the lines of "did you see that? He had no one near him and still missed it. Ha ha". The comments were about various boys but not his son . They weren't just said within earshot of the parents but the boys on the pitch too
Should I tell him to STFU keep his comments to himself or wait for a coach to tell him or do something else? Its only the third week that DS has been (and my first week accompanying him) so I'm not sure how to tackle it really. What also complicates matters is DS is really good friends with this Dads son.
What would you do?
