The only thing I can see the teacher objecting to is the swearing. Otherwise she's literally doing exactly what she should, and you're punishing her for it.
Reminded me of:
"I don't mean without my vagina like I didn't have it with me, just that I wasn't... *displaying it* while I was at Starbucks. Just to clarify, I *always* have my vagina with me. It's like my American Express card. (In that I don't leave home without it. Not that I use it to buy stuff with.)"
But that's the thing, being overly polite to someone who's so insistent despite not having any protection with them may lead to them persuading you in the end, especially if alcohol is involved. Being rude to them will surely make them fuck off, and this girl has the right idea.
