Tell her to go **** herself because you shouldn't have to prove anything thing to her dipshit ass anyway

Tell her just because she is actually Scottish posing as Irish and see how she reacts to that :)

You should make fun of her anyway she sound like a b*tch if she won't actually believe you.

My grandfather never lost his Boston accent. He passed away in 2001 and hadn't lived in Boston since he moved out west in the 1940's.

You could prove her wrong either with your knowledge of Ireland or by having your parents correct her.

Good luck on any exams!

Swear at her in Tagolog!

Perhaps then your next attempt at an explanation should be a sincere and heartfelt "Well then, go f**ck yourself! Let's go see the principal you paranoid psycho insecure bi**ch". Or maybe better (so you don't get on her level) would be to get a brief note from your parents backing your story and go see the principal and demand an apology from her in front of the class. That way you will for sure be harassed and get a bad grade no matter how well you do. So, in reality, get the note from your parents and just leave it on her desk without ever commenting on it. And if that doesn't work have your parents call the principal. But doesn't the first one sound great!

Born in Ireland... easy copy your passport and show the woman. And kindly inform her that assuming your accent is fake because it does not typically fit your etnicy is shallow minded if not racist.

Scumbag teacher..
