Pay Attention to Yourselves and all the Flock 1991, p22/23
Newly associated ones are especially in need of attention.When they first come to the Kingdom Hall, new ones may feel like strangers ; we want to change that feeling to one of warm friendship . If you notice a new one standing by himself or talking only with the one who studies with him, take the initiative to approach and greet him and introduce him to others . Teach attendants to greet new ones, and occasionally remind them to do this .
Such personal interest lets them see that genuine love exists among Jehovah's people .
Train all the brothers and sisters to take the initiative in approaching new ones and getting acquainted with
them. So that you may encourage and help others, be sure to arrive at the meetings early and stay for a while after the program. You can associate with new ones at other times also, perhaps visiting with them in their home or yours. Such personal interest lets them see that genuine love exists among Jehovah's people. (John 13:35)
It also fills the void created when they cut off former associations and worldly entertainment.
