Initially this was going to be a rant. But instead this is a proud dad moment.
My son is currently the SPL. Last month the theme was canoeing. For a variety of reasons, only 2 weeks were spent on the theme before the camp out and then moving onto wilderness survival. One of the new cross over parents posted a picture from the weekend, and the comment that they need to finish the canoeing MB and the youth leaders need to set it up and get the troop to finish what they started. Several of the new parents liked the comment.
My son replied that unfortunately they already have things planned that the Scouts need to get ready for, specifically the next camp out and the camporee.
I think my son handled it professionally and courteously. very glad about that.
Here's the irony. While the goal was not to earn Canoeing MB, he did plan on spending more than 2 meetings on the topic before the camp out so it would be possible for some to finish it. Adults coming up with last minute stuff interfered with those plans.
