answer:First I must say this…ew. Is she leaving blood on the toilet or is she leaving old tampons in the toilet? Both are pretty gross, but if she’s bleeding all over the bathroom, that’s a whole other issue. I’m going to assume you mean she leaves it in the toilet. If she’s been confronted about this and simply doesn’t care (how can you not be embarrassed by someone bringing that up?), then she’s obviously just hard headed and still too immature to realize exactly how disturbing that habit actually is. Maybe when she gets older, she’ll get better. But then again, some people just have gross bathroom habits. I mean, how many grown men still pee on the toilet seat and just leave it? I know my answer probably wasn’t very helpful, but if you’ve already spoken to her, what else can you do?
