I used to live in a BIG city with about a dozen KHs. A friend of mine was looking for her sister who has mental issues/schizophrenia and was on and off the streets in my area. For a time we heard she was studying and attending one of the halls. My friend had a contact in the hall who I guess was looking after the less fortunate in the congregation. One time my friend specifically thank her for her efforts in looking after her sister and others less fortunate. The sister said:
"Well, we gotta a whole row of em."
