Most common catchphrase you'll hear in the Local Churches is poison. If you are one currently meeting in the local churches, you're wary of ex-members because you don't want to be poisoned. If you're an ex-member you're wary of current members because you don't want to be accused of trying to "poison" them. In other words the concept current members have of ex-members is they will try to convince you to leave which is furthest thing from the truth.
So there are avoidance tactics employed. Still having compassion you don't want to intentionally offend the other. Really this all comes down to fear of man.
Ones may have spent time together in the meetings and away from meetings, but the common denominator for their friendship is the LC culture. As one stays in the LC and the other goes, the basis for their friendship is gone.
