It's quite alright. My professors do say I'm being a nuisance when I ask things.
In my time, there are some wizarding schools which are only for boys, or only for girls. Hogwarts isn't one of them and never has been, and we even take most classes together, although boys don't study domestic magic and that sort of thing. We have extra Latin and magical theory instead. I was curious about Durmstrang, but it's quite understandable you don't want to talk about such trivial things when you aren't well.
