I'm just going to preface this by saying that I know I could have used my voice and that I'm a bit of a drip for not doing so but...
I was in the shower at the gym/swimming pool and there were kids screaming in one of the shower cubicles. I feel like I have quite a high tolerance of children having fun and being noisy but this was awful, high pitched, screaming. The children were both able to use words so not toddler age. I'd say ages 6 and 4. The older one was telling the younger one to be quieter. There was no parent/carer in the shower area at all.
A few minutes later, their mum came in and asked if they wanted 5 more minutes and they agreed. She left the shower area again. At the time I was thinking it was a bit irresponsible and irritating of her to leave the children unsupervised but it's sort of par for the course at this particular gym.
Then the 4 year old banged open my cubicle door and asked me to give back the ball that had rolled under the door. I was shocked as I was obviously naked and so was he. I gave it back and asked him where his mum was and to go out to her. He didn't and just went back to the shower with his brother.
I left and went into the changing rooms and after a few minutes they both came out as well. The older child told his mum that the younger one was going into the cubicles when people were in there. She just said "oh name, you're not supposed to do that"
It just pisses me off that these children are being left to run amokin the showers with no regard for other people but also that they are being left in really vulnerable positions. What if he walked naked into a pedo's shower cubicle? How risky is that. What are these children going to know or understand about boundaries if they're not enforced or if they're not supervised until they can behave appropriately in public?
AIBU for thinking this mum (and many others like her at my gym) are fucking morons for not properly supervising their kids.
