Written on the subway walls

"This is an exhortation both to the younger and to the older, more established, men of the congregation. To you younger men: Break out of your gang, and get to know the older men of the congregation, seek their counsel, learn adult responsibilities from them. And even more importantly, to those of you who have established callings and families: Make the effort to know the young men of the congregation. Introduce yourself at church; invite them into your homes; invite them out for a cup of coffee. And the same goes for the young women and older women of the congregation."
