He responded to my raised hand by calling me by my first name [not CoCo]. That was done at my hall only for interested persons who wished to participate. Even little dubs got the bro' and sis' titles.
I knew a sister in her 60's that must have ticked off the WT conductor. She would raise her hand and he would ignore it. She went up afterwards to find out why. "I just forgot your name." Next Sunday, same scenario. After 4 weeks, I looked over and saw her pull out a piece of paper, It said "Sister Older" in 3 inch black letters. She sat in the middle of the second row where the conductor could not miss her. When she raised her hand, he could clearly see her name on the paper, the reader could clearly see her name on the paper....he called on her and from then on.
On another occasion, a younger elder conducting the WT study called on an 80-year old sister by her first name. As she grabbed the microphone, she said, "That is Sister Frank to you, John," and then gave her answer.
I miss those older women. They were the backbone in many congregations where there were no men or no capable men to handle the administrative duties.
