happy-n-alive- Many Jw's do not understand boundaries. They are trained to ignore them. If you don't want people hounding you, you need to tell them. I would tell them do not call me at whatever time of the morning or not at all. That's up to you. And you definitely do not owe explanations to strangers at the KH asking where you've been.
And if you feel like you are being mafia- chased now, how do you think you will feel if you continue associating with them? JW's are a high-control group. In other words- a cult. Be careful.
