@Ceili,

Yes, sometimes wrong is wrong, Ceili but when it comes to language, neither you or your dear sainted mother are/were capable of knowing when that might be. Don't be misled into thinking that the childhood knuckle smacking for perceived errors had any veracity.
When you hear a person speak another language, you can't follow their meaning or accent. It's no different for some dialects.
I've read that
ain't was, at one time not too far back in history, the choice of upper class Brits and it was shunned by the working class. Whether this is true or not really isn't important.
ain't is simply one grammatical choice, actually an easier one because one form suffices for all the pronouns.
