Spinoff from the prncss post- Talking back

What do you do? I find myself sounding like MY mother too, saying "you are being fresh!"

I get "Get over here! RIGHT NOW!"
or, she says "don't talk to me like that!".
She will also tell me to do something, then count to 3........
I really don't yell so I look for alternatives- but she uses them all against me!

She is also EXTREMELY rude to strangers. They say hello and she yells various things at them, like "Don't talk to me!". My grandmother lives in an assisted living. Whenever we go to visit she yells at all the old ladies
It is really embarrasing actually. She knows it is wrong because I will tell her and she will ask "did I hurt her feelings?"

Anyone elses kid bratty like this? how do you handle it?
