Big Group

I can’t function in a big group. I’ve decided. I simply can’t. What’s the ratio of talking and listening? How do the people in it get cut into conversational duos? If everyone is on one topic, How do you determine the main orator to whom everyone responds? Where’s the timer that determines when you become the orator? What if you get really excited and simply have to share something but your proposed topic flops and falls down the stairs? These questions plague me when I have nothing better to do than plague myself.
