"Don't You Back Talk Me!"

What the hell gives old people the right to talk to you wild reckless without any repercussions? I've never understood this...

My grandma feels that she can say whatever she wants to me but if I even fix my lips to say "Grandma, that's wrong..." I get hit with the whole "don't you back talk me!!!" By no means am I advocating that I should be able to say whatever the hell I want to to my grandma... but I don't think it's fair for her berate me about a bunch of shit she has no idea about without the privilege of defending myself...

It's not even a respect issue... I think you should always be respectful but old people seem to just be able to think they can get away with murder because they're elderly... I remember when I was working at UPS and they would just talk to me however they want to... so then I start getting pissed and I'm talking to him how they're talking to me... that's when they come with this "Well, I'm 89 years old and you should have some respect..." Motherfucker, for what? You gotta give respect to earn it, B... whether you're 12 or 92... that shit is universal...
