I think this is a good indication of what JW "friends" are like. They're just more WT "tools" to pressure conformity and sticking with the cult.
Something to remember is that they only have power over you that YOU give them. You're upset now because you still allow them to upset you. And I think we all have been there. WT has a mastery over fear, obligation, and guilt that keeps people enslaved to their craziness.
You really don't have to tell them anything if you don't want to.
