something they don't often talk about in YTT

I've been instructing for about 10 years now & one thing that has always been a challenge for me is quieting a room at the start of a class. It gives me a lot of anxiety.

Naturally, nobody should be chatting away like that especially so loudly but humans do what humans do.

I find it super awkward trying to tell everyone to be quiet (this also does not happen every time- it's only happened maybe a handful of times over my years instructing) Most often people are mindful and quiet at the beginning of class awaiting the start but occasionally there is an extra large group and they are all over the place!

Has this happened to anyone? What do you do in this situation?
