Nah this was a cult right?

Okay I was practicing with my classmates today and uh bunch of korean ahjummas stepped in, mind you my group was mainly girls. Important detail. Anyways, they came up to us and I wanted to test my korean skills and tried to talk with them and I was ignored? They talked with the girls instead?? And asked "do you know jesus?" and they couldn't understand cus korean accent. Only when my friends pointed out that I knew korean was when they listened. I told them that we are practicing cus like I had a bad feeling abt them. They kept talking about jesus and I politely told them that sorry we can't help or whatever with that, we are busy practicing.

They left us alone eventually and just said "god bless you" as they leave. Then after they left I notice a black car just staying near the spot where we are practicing. I asked my friends to move somewhere else and boom when we left the car also left (?)

My friends also noticed it too and think those ppl might have been cults. What do u guys think?
