For context, I run a local brownie unit, and was trying to get the girls to listen (which, to their credit, most of them did) while to of our adult volunteers continued to chat away loudly to themselves.
I told them assertively to stop talking as I was explaining something. They stopped sheepishly, then irritatingingly continued to chat slightly more quietly. I left it as I didn't want to create any sort of scene, but at the end of the night once the girls had left, made a point of telling them how difficult they'd made it for me when I was trying to set an example to the girls.
One of them retorted "We are adults though, not girls", which I just wryly smiled at and essentially ignored.
I'm actually really upset at thr disrespect and immaturity of the response (as I see it). Yes, they are volunteers, we all are, but when I'm trying to run unit they are not above basic respect for others.
I hope I make it very clearly every week how much I appreciate their help, but this has irked me.
Maybe it was unreasonable, but they do it every week and it was very distracting.
