Why are you replying to me, and not to the OP who mentioned outdoors pursuits as a way to meet people?

If you recognized someone's face in a restaurant, then they weren't a total stranger. But the OP made it sound as if talking to a total stranger is an option, when it is simply not welcome in all regions of the world.

I never said going outside to meet people, I said that you can do those activities with people to support friendships. You probably have to establish the acquaintance somewhere else first. Like sports or an art class or something else in the community.
