What I've told you several times is, you're an equal partner in your feud with Andrew, meaning you're a 50% contributor. Unfortunately, you refuse to accept it and deflect and make excuses such as, if he learned how to banter properly, which is your go to one.
Even people like LUC Park have told you to knock it off on several occasions, the latest time being yesterday. Naturally you went on the defensive and said, why point the finger at me like you're totally innocent and it's all Andrew's fault.
One last thing, repeatedly telling someone their dementia is getting worse is not only rude but ignorant, but I'm sure you'll disagree and explain why it isn't.
