Hi, Cranberry.
This situation is loaded in just about every direction I can think of.
I guess it all comes down to what you want to get out of it.
I’m going to assume, if you’re anything like I was at 19 or even at 50, breaking loose and asserting your autonomy in the world is a strong motivator. Any situation where someone else’s rules or way of doing things infringes, is grating – particularly if their way doesn’t make sense from your point of view.
I would say that, ultimately, the issue is power. As long as you feel they have some power over you, the natural tendency will be to push back in some way, like playing your CD’s loudly while they’re in church. If you can get to a place where you feel their opinions and ways of doing things don’t matter any more, it will be easier to let them be and do their thing without your clashing with them.
One way to gain a sense of power over someone is to present them with nothing to disapprove of or argue with outside of matters of important principle.
People seem to love an argument. If you choose carefully which arguments you actually want, and systematically avoid controversies you don’t want, you’ll probably find most people are easier to get along with and you have more influence and credibility when you do choose to stand up for something important.
I would suggest that playing your CD’s loudly during church isn’t really an important matter of principle. If you think it is, I would then suggest that you consider the likelihood that treating little things like that as matters of principle that must be fought over dilutes your credibility when you want to discuss things that are much more important.
The more you can pick your battles thoughtfully and be otherwise as nonthreatening as you can, the more you are likely to discover that you’re in control because you’ve chosen not to be pulled into a needless controversy. You’ve chosen not to become hooked, which means you’ve chosen not to lose your power in the situation.
On the other hand, many people seem to need controversy for no other reason than to feel connected with the rest of humanity. You’ve got a situation there that’s well suited for that, if you want to play it that way. You can go round and round with your grandmother and the church folk over this if it serves your purposes.
I think the best solution would be if you could find a way to accomodate the church people’s activities without feeling imposed on yourself. You do gain power over them if you deprive them of anything trivial to criticize you for. And, misguided though they may be from your point of view, church is important to them, whether you approve or not. If you figure out how to accomodate them without feeling taken advantage of yourself, you may find that they give you more leeway from their side, too and the whole exchange changes tone.
FWIW,
Jerry
