I honestly have given up trying to understand other people’s actions.
Now I just focus on my self care and watching that I have reasonable boundaries etc.
So she brought cookies ? Ok to me that’s odd .. then she says they are disgusting ? Umm well okay guess that person is a bit odd, mentally just move passed it.
Who take pics why where and when ? Social media posting? I’d just ask for clarification and if I felt used, excluded or judged. I’d either just accept the guidelines and still go if I found any of it enjoyable. But it seemed for you that it wasn’t so you left. Sad you never heard from anyone but life isn’t really polite anymore. That’s on them.
I’d not let that stop me from stepping out of my comfort zone and socialize. I might be a bit slower to take on a big part of the group.
