Why does it seem as though my sister purposely always disagrees with me to make herself feel superior/smarter?

I can say something like “Cleaning isn’t OCD in itself but the OCD manifest into cleaning as a way to deal with the OCD.” And since she went to school for psychology she’ll say “I went to school and studied that. That’s not the only form of OCD.” As if that makes what I said to be untrue. Or, more recently, I was saying how most or even every decision we made or make in life was influenced by our homes. I was basically saying everything starts and home, Meaning, your home is what essentially creates you. She had to disagree by saying “Well no. some people grew up very privileged and never wanted for anything they just were crash test dummies.” As if having parents or a parent that took care of you was gonna automatically make you make good decisions considering life is beyond the material things. It can get very frustrating whenever talking with her because rather she consciously does it or not, she seems to always want to control and take control of the conversation to feel better about herself.

She went to school to be a wright fighter there's no way you're going to ever win why would you even try it's not worth it when she starts your crap you have to look at her and say hey how long did the doctor say you were going to act this way I'm not one of your patients I'm not one of your clients I'm your sister did you forget what that was or do you now treat everybody this way how much do I owe you because you suck you're not getting paid LOL now you can't say that

Look at you don't have to prove anything to anybody except for yourself it doesn't really matter at the end of the day does it she's going to battle with you no matter what because she has the credentials to be a right fighter. You will never win when you go up to a right fighter because they will change the story they will go from one topic to the other topic to the other topic

The only way to win is not engage because that's what she's waiting for she's waiting to talk she can't get enough talking in she cannot get enough of herself so you need to ask her how long did the doctor say you're going to act this way

If you want to win do not engage in any type of conversation like that she will turn it into something that he'll turn it into anything just to keep her lips moving she will go crazy if you don't engage she will make you try to engage don't do it you win

She's your sister. Sibiling rivalries and jockeying like that are pretty common.

I don't know some people are like that. I think it makes them feel smarter to say that your wrong, sorry that it's your sister when I have friends that do that I slowly cut them out of my life.

Some people get their rocks off from being argumentative. Sad I know.
