"Well, sometimes the men and boys might be around the campfire, and they might be talking about things that the moms shouldn't hear."!!
Maybe I'm wrong on this one. I am the SM in our troop and I would not allow these conversations anywhere on scout functions. I know the boys will tell them in their tents but not where the adults are present. Our role as role models does not fit with this statement.
We do allow the women in our troop to attend our outtings. I do, however, tell them to be cautious about correcting the scouts and also that we do not allow a parent to correct their own child unless it is a matter that needs addressing immediately. The boys do not have a problem with this.
