As stated before, it's usually the sisters who initiate and organize any charity. The spiritual arrogant elders are way too busy and important to mess with details like the flock under their "care".
Very recently a number of sisters initiated and implememted a schedule to care for an elderly handicapped sister's even older invalid mother while the daughter was hospitalized. Strange thing about it was the sisters doing all the work, including overnight care, were also all older woman in their 50's to early 70's and not themselves the pictures of health. The younger women, the healthy son, and every single appointed brother couldn't be bothered with interupting their schedules to help.
I have notice it always seems to be the older, less healthy who do the most for others.
