Brother Stupid Phone Calls and Hypocracy

Brother calls me and tells me that water is leaking on the roof from my sisters air conditioner. I knew this so I say, "I know."
He asks, "It's not supposed to do this?" and again I say, "I know."
He asks, "Didn't you say you had the air conditioner serviced?"
I tell him, "yes, I did but the pipe that the water drains into through the house is clogged so tha water can't drain through it. I have to get a plumber or someone to fix it."
He asks, "shouldn't the Air conditioner service guy have cleared the condensation line?
I say, "He did but he can't clear out the plumbing in the house. He doesn't have the tools for it."
He says, "Well that has to be fixed."
I say, "I know."
He then says, "The air conditioner guy should have fixed it."
I say, "He doesn't fix plumbing."
He says, "What does plumbing have to do with it. It is water coming from the Air conditioner he should be able to fix anything dealing with the air conditioner."
And here is where I am starting to get irritated because he is starting to repeat himself and shows he isn't listening to me which means my voice starts to get higher pitched and a little louder and I say, "I just told you that it is the plumbing that is clogged, he can't fix the houses plumbing."
And he says, "Don't get short with me. I didn't know it had to do with the plumbing."
and I say, " I just told you it was the plumbing the pipe running through the house where the water drains.
And he says, " You started out being short with me saying I know, I know in that way."
And I say, "What am I supposed to say, that I don't know when you tell me something I know?"
He says, "but you said it in that way like, 'I know'. How am I supposed to know if you know or not."
And I say, "I guess by me saying I know like I did. Am I supposed to call you and tell you every thingI know so you won't call me and ask me about everything?"
At this he paused for a second and then hung up.
This, if you remember is the same person who called me back when I put down the receiver after a phone call was over and he called me back and acused me of hanging up on him and how it was rude. But I had only hung up after we had finished our call and it was over but I guess he dint in his mind get to that point so when I hung up the phone all he heard was that I hung up but whenI asked him what more he had to say he told me nothing that the phone call was over but when I hung up he felt like he had been hung up on. I guess for him the phone call isn't over until he hangs up and if he still has the phone up to his ear when you hang up even if the phone call is done then you are hanging up on him. And yet he has now twice hung up on me in the middle of a conversation for whatever reason he decides it is a thing to do.
I don't like talking to my brother so any call is unwelcome but if they are not stupid then it is alright and over and causes no anxiety, But these are rare maybe one in 6ix or seven calls. The rest are irritating or insulting or stupid. He calls me for the most idiotic things or for things that I can't even understand why he calls. And often insults me or treats me like an idiot or asks things that either need not be asked or I can't answer or he asks the same questions over and over in slightly different ways to try and get the answer he wants and then he gets upset with me when I attempt to answer them or get irritated with it because I'm not the type to hang up on someone. Maybe I should change that and just hang up.
The hypocrisy bothers me the most. It is a pet peeve of mine to begin with but in his case it shows how little he considers my feelings and puts his own wants above everyone else. You can't hang up on him even when the call is over without hearing about it and being called rude and taken to task but he can hang up on you for whatever reason he likes. He can continue to question you over and over about the same thing until it makes you irritated and angry but you cna't ask him anything without him then treating you like an idiot because you don't already know whatever it is. I know he has information and knowledge that I don't but I have given up trying to learn anything from him by asking because he goes into this kind of teaching or educating mode that treats you like you are maybe seven years old. sometimes I only need a yes or a no not a lecture on how stupid I am or questions on what I already know so he can then tell me what I don't.
Argh, went into rant instead of only putting the phone conversation down. And you have read it all before. Oh well guess I needed to vent some.
