I know I got the shot for a strange reason. Like others have said, people won't accept you for your decisions, then they're not really your friends, and that is true. But I don't think the isolation that comes with it is worth that to me. I've had to get vaccines I did not want to get to be able to attend college here in Texas years ago, I had the same line of thinking then as I do now: At what point do I draw the line in conforming to society?
I don't like or agree with a lot of the things I have to do everyday, but how am I supposed to help others and learn if I'm a social outcast? I've always thought about WWII and all the stories I'd hear about those who pretended to support the nazis just to helped others from the inside. Hopefully in a less dramatic sense, I feel like when the doodoo hits the fan people are going to need help, and if I'm a social outcast I won't be able to do that. Gurdjieff said the best place to practice the work is in your own daily life, perhaps playing these games of society, within reason, will help me wake up.
This is what I'm thinking, and that's why I got it. Maybe it's way off and I'm just coping, and if that is the case I welcome a different perspective from others for me to consider.
Well, I wouldn't stress too much about the shot if you've experienced no ill side effects.
I wouldn't either upend your life, specially your social circle, at this moment. I agree with you, that one must make the best effort to behave in such a way that will grant one access to company, one does not have to agree with everyone and with everything people say or think in order to have a civilized interaction with them.
You know your social situation much better than anyone here. And with the upcoming turmoil, why antagonize anyone, specially if it's people you have knowns for years.
What I would do though, is to at least meditate about how you have made the choices of friendship, again not to upend your life and isolate yourself, but mostly to understand it for yourself. Maybe there's an underlying fear of being alone, or an issue with boundaries that makes it more appealing to sacrifice certain agency in the name of company or belonging.
There's nothing wrong with that implicitly, but it can lead to situations like this one, where you're surrounded by people who put conditions upon you to consider you a friend or grant you the chance of sharing a moment with them.
We all must do this in order to belong with anyone, even interpersonal or romantic relationships, there's always a sacrifice of freedom in the name of company, but it should remain, hopefully, balanced, where you're not loosing yourself in your group, nor are you completely locking yourself away in your freedom.
You can't learn everything you need to learn in either of those two extremes. As the saying goes, you'll go fast if you go alone, and far if you go together... but what I am proposing is to go at decent pace and to a decent distance.
So, at least meditate about it, and perhaps recall past occasions where you've made similar compromises and what were the reasons behind them, and be honest with yourself, I think it's better to have honestly visible mistakes than a perfectly calculated life with no mistakes, personally.
My own experience, and I think it's a bit of my own rebellious personality, if someone wouldn't want to hang out with me due to a mask or vaccine, I wouldn't hang out with them. Or I would live by example and shake hands and give hugs, despite their fear. Or if there's a vaccine mandates, I would simply hold my ground, and if the answer was no, then the answer was no.
Sometimes, it's painful, but the only way to find out if people want you in their lives is how much of a compromise they're willing to do in order to ensure that this is the case.
And lastly, also meditate on the idea of being surrounded by people who want the best for you, and maybe ask if your current social group fits that description, mind you.. they probably won't entirely, it's not black and white, most of them will fall on grey. But it's a good thing to consider, I would say.
To reiterate, I am not trying to reproche your shot decision, nor your friendship. I am simply suggesting a few questions to ask yourself for you to understand a bit better where your feet are planted.
my two cents.
. I tell myself he can speak for himself as it's his wedding ... no one will be asking me to say a thing and since they won't be, I won't be saying a thing. Deep breaths
