I'm not going to take one of my player's complaints about being uncomfortable seriously.
Why aren't you going to take them seriously?
She's always complaining about her period.
It's inappropriate to assume that your player's complain about her period isn't serious. If she says she's uncomfortable because of it, you should believe her.
She's just a drama whore.
You are being a real jerk here. Don't just write off her complaints.
