I take my kids to a family group and today was "family photo day". Every day there is group, a staff member texts to confirm who is coming and gives any additional information needed. We text each other and confirm I'm coming. I get myself and the kids ready for photos and as I'm driving, my husband calls and said "hey, is it at (the building where groups are typically held), I took some time off work so I'm coming." I didn't get addiontal texts from the group so I told him it was at the building. We get there, are waiting maybe 10/15 minutes. Finally a staff member comes out and says "oh, everyone is at this location" I'm pissed because 1) why wasn't I told this information? 2) my husband took time off work but now doesn't have enough time to go to said location. Before he leaves for work he asks if I'm gonna still take pictures. I told him I'm not sure as I got everyone dressed up and I kind of want to go just to let them know what they did was not ok. At this point, I'm remembering a conversation I had with another parent who has has troubles with a couple of staff members and the group eventually excommunicated her. So now I feel like it's an opportunity to stick up for myself and see if what happened to that parent is true. I go to the group. I see 4 other families there. The staff member who was in charge of texting came up to me. I said with an annoyed look and tone, "would have been nice to know we should have come here". She responded in what I felt to be ingenuine, "oh sorry, I forgot, haha" and walked away. She walked about 30 meters away to where her boss was. At this point I'm chatting with another mom who was curious as to what happened. I explained the situation and she said, "wow they texted me 2 days ago". Then the texting staff member yelled from where she was, "are you ready to get your photos taken?" Everyone who was there looked right at me and I calmly said back "no, I need a minute to calm down so I can be ~zen~ in the photos" with a vexed smile. The staff member (still beside her boss) just side eyed me and said "okay" with a ms Rachel tone. I take my photos and go back and sit with the other parents. No staff member came to check on me after my comment. The boss didn't come check on me. I feel like this confirms what the other parent has gone through is true. But I need the reddit verdict, was I an A for saying the zen part? I tried to say it calmly but she also shouted the question so I had to raise my voice as she was far away. AITA for showing up? Should I have just missed the group and let my absence be the voice for me?
