1. Ignore her. Literally. Pretend you have gone deaf. Then pretend that you have gone deaf and blind as she yells, ups the ante and makes weird gestures. Then, when it is quiet and calm, behold! Your hearing and sight have returned!
2. Use the Broken Record Technique. It could be any line. Like, “It’s OK, I forgive you”. This is an alternative to Ignore.
“That’s stupid!”
“It’s OK, I forgive you.”
“You’re stupid!”
“It’s OK, I forgive you.”
“IT’SOKIFORGIVEYOU!IT’SOKIFORGIVEYOU!!”
“It’s OK, I forgive you.”
3. Another technique is to say “You’re right” to every insult and “I don’t know” to every question. Eventually she will tire herself out because she have no kick back, no fight. (Obviously she’ll know “You’re right” is meant ironically).
Basically you want her to tire herself out and soon learn it’s not worth it.
And, moving would be a GREAT option!! As everyone gets older and sees each other less respect usually grows.
