I take my DD(3) to a toddler swim class on a Saturday morning. It's usually a mixture of mums and dads in the pool, separate changing areas obviously. However the changing areas open directly into the corridor where other parents (the non swimming parent) tend to congregate and wait. DD's class is mostly dads with just me and one other mum, so just me and her in the changing area after the class today. I'd already removed my costume under my towel and was drying myself off, obviously naked under a towel, chatting to DD. Next thing, the other mum opens the door (her costume still on) to have a conversation with her male partner who was waiting in the corridor whilst I'm standing feet away under my towel naked. I wasn't directly in his line of vision of had she opened the door any wider, I would have been (hard to explain without a picture of the set up). It was only a matter of a minute or so, she was from what I could gather trying to get her toddler to go with dad so she could change by herself.
AIBU to have been annoyed about this? Surely if you want to have a conversation with your partner and you're in a ladies changing area, with another woman who you can see is mid getting changed, go out into the corridor instead?? It just felt like an invasion of my privacy, I'd never have opened the door to casually chat to my DH outside the door of a changing area if another woman was changing.
