I only have a mild one. Even though atheist, I briefly dated a Lutheran. She wanted me to come listen to a public event, where she would be singing christmas songs in her church choir. I decided to go to support her. Was a newly divorced dad and with toddlers. She knew this, but when I showed up there was no nursery or place for them to be. I guess in some churches you’re supposed to hire a babysitter for functions? Was news to me. So I did my best in a foyer (didn’t even enter the chapel) but eventually my kids got bored. Latecomers had overflowed into the foyer and people complained about them being noisy and started mobbing me, so we left. She dumped me because I guess they could briefly hear my kids from inside the chapel and it was considered disrespectful. So I had obviously violated their norms and was thus in the wrong, but at the same time if they couldn’t handle kids making noises at a public event then it was never going to work out, so it was all for the best.
