Is this dialogue correct and natural as is?

Hi teachers, could you please check if this dialogue is correct and natural as is?

"Stop using those kind of words around my daughter."

"She better get used to it."

"Get used to what?"

"Hearing swear words. She's starting school next week, and other people's kids curse, so we have to learn her that it's completely normal and not something to get upset about. I know you're a priest and that's affected her, but I assume you want her to fit in, don't you?"
