I totally agree with prohibiting behavior, not age. People don't like having to confront someone behaving poorly so they frequently add rule after rule. If an older person is talking all the time and disturbing other people, let the guild president say something. If a child is running around and disturbing others, let the president say something. The rule,should just be "listen to the speaker (if there is one) and do your sewing without distracting others.
We we have a few young women in our ASG meeting with young children. We haven't had an issue, probably because the expectation is pretty well established. I have heard our leader, a former school teacher BTW, call out adults who were talking to,each other loud enough to disturb others. Good for her!
