This friendship you have is only possible because you state you have no religion. You and your family are viewed as possible converts. A JW would not have a friendship with a person of faith. Nothing a JW hates more is a Christian of another church.
The real fucked up part is as a JW you are required in hand in a time card for your witnesses hours each month. If you hang with this family for let’s say 3 hours and they once mention something from the bible once it’s like they had a three hour bible study with you. That is how they will see it. What is even more messed up there is mostly a file on you to see how you are progressing . Don’t be surprised if one day they don’t talk to you again. They will be under orders from the elders you are a lost cause .
Think in full of shit. Ask them about the time cards.
Dude you are nothing but a mark.
