When you grow up in it, you think you have true friends. I did anyway. But it is conditional friendship. Conditional that you remain active in the "truth".
They're not really friends. They're co-workers. We were all marketing reps for the WT publishing company. We had to work along side these people day in and day out, so therefore you strike up some friendships, but by and large they're not real close friends. Acquaintances that you like maybe.
When you leave a job, how many of those co-workers do you keep up with? A couple maybe. Those were friends. The rest? Co-workers. Acquaintances.
Same with the JWs. Leave a congregation even. How many of the people in the old cong. do you really keep up with? A couple maybe.
Now... leave the religion altogether. How many keep up with you? You're lucky if it's a couple. Even if you try to keep up with them, they'll cut you off. They weren't friends. They were co-workers who put the company rules in front of friendship.
