IMHO its basically a case of they can't talk to you casually, but its ok to discuss BUSINESS issues. My mom tells me that all the time. When it comes to calling her up, hey mom how you doing can't talk to me, but when she needs me to pay a bill for her, she can call me and ask me to do that, its business.
i came back to add these little tidbits too,
My dub aunt had got a ticket once with the police dept I worked at for parking in a handicapped parking spot (for only a few minutes she says). Mind you this is the aunt that whenever we're all at my non-JW grandmother's house she never acknowledges me. But anyways she never picked up the phone to call me herself to ask me if I could help her get the ticket fixed, she had my non-dub uncle call me about it. First I was like, she couldn't even pick up the damn phone to ask me herself, but she wants my assistance. HELL NO!!! My uncle tried to get upset with me because he didn't understand the whole df'ing arrangement and thought i was dead wrong for not helping. I didn't even bother to try to explain, it was a waste of my breath. Long story short, she had to end up paying the ticket...
and maybe i could have helped but then i thought about this situation...
I was working at the time for the State Police as a dispatcher, anyways ran a plate and it came back to dubbies I knew "really well"(my used to be best friend when I was a dub). Well I called the trooper on PC(private call) and asked him what was up with them, speeding or something??? I forgot what the actual violation was but he ended up letting them go because I said " I know them, they're ok". they were on their way to an assembly that day and the husband had forgot his license at home (so i got them out of really hot water) but since trooper let them go they were able to arrive at the assembly on time and stuff. how do I know all this, well my ex-best friend found my mom at the assembly...and then told my mom about what had happened on their way to the assembly....she never told my mom to tell me thank you or anything....i guess i was back to being an evil df'd person again....i bet they chalked it up to Jehovah used me to tell the trooper i knew them so he would let them go....but a little while after this, i saw that same dubbie and do you think she even gave me a head nod or any recognition....pissed me off, and yeah i know they didnt ask for the help, but help was still given....
So basically it all boils down to, if they need something from you they feel free to ask, or get someone else to ask, but besides that you're the gum on the bottom of their shoe..
