I believe Sathy Chithi is celebrating her retirement with a few of her siblings around this week at Erode. She is treating them to lunch or dinner, I'm not sure. Gifts are being exchanged. I believe maami has fought her way to be with her sisters-in-law to treat Sathy Chithi in turn. 
Sathy Chithi is such a darling, with her child-like ways and the joy she takes in giving happiness to her sisters. I've seen her give complete and total medical care to them whenever the exigency arose. She sees to it that she is always there, by their side, when they are under medical attention, surgery or sickness. My heart has always warmed to this beautiful lady, with that charming smile! 
God bless my dear chithi.
