As an atheist, but someone who grew up in places where there were constantly missionaries, I’m so…

Latter-day Saint missionaries are posted to pretty much every congregation world-wide. For Manhattan, I know we have around 13 congregations on the island and each congregation has at least one pair of missionaries, but most have two. My particular congregation has one set of Elders (boys between 18–25 generally) and one set of Sisters (girls between 19–27 generally). They have a set income for food each month which is pretty low and that’s supplemented by members of the congregation feeding them throughout the month.
