What do you think of me putting someone on speaker and turn the volume down so they sound small when I argue with them on the phone?
That seems like a rude things to do. Why do you want them to sound small?
I hate that someone blocks my view, she acts like I'm too stupid to do anything about it.
I think that you should just try to ignore her. It seems petty to argue in such an immature  way anyways.
What do you mean, if someone did that to you, wouldn't you get annoyed too?
While it's normal to feel annoyed about things from time to time, it's wise to improve a problem instead of trying to make it worse.
