My grandmother had six sisters. During the holidays they would gather in the living room to chat. I would come in and quietly sit on the floor watching and listening. Many times all seven of them would be talking at the same time. That always blew me away. Great entertainment but I dared not laugh.
LOL. My father-in-law and I did something similar, we'd hold up one finger for each woman talking at a given time. Kind of a "gab index". It averaged somewhere between 2 and 3.
Later we played another game: "Let's see how long it takes until one woman says something that makes no sense but all the others know exactly what she means". It took less than a minute. My mother-in-law said to my wife: "You know, your mother". She meant "My mother, your grandmother". All the other women understood and the conversation continued until my uncontrolled laughter disrupted it.
