a very important distinction i have tried to teach myself and my kids is:
"is this person being annoying to you or are you just feeling annoyed?"
sometimes people do go out of their way to annoy you and that requires a different response! but a lot of the time we attribute maliciousness or ignorance to someone when we are simply feeling annoyed as a response to something that has nothing to do with us. maybe they're just enjoying something in a way we don't personally like, or maybe they're having a bad day, or maybe they have habits or personality quirks that rub us the wrong way-- and they aren't thinking about how it impacts us at all! and in many situations, they shouldn't have to! it's not a person's job to make sure they never do anything that could be perceived as annoying to anyone else.
and learning to tolerate feeling annoyed is crucial. de-escalating your own sensation of annoyance and refusing to treat it as harm/discomfort is an important step in getting along with other people and guarding your perception of your own acceptance and belonging. many people on tumblr express social anxiety-- and i gotta tell you, if you keep legitimizing your own annoyance all the time as a serious problem (instead of a small thing to vent to a friend about/get over/ignore), then you are also going to end up fearing that you are frequently annoying to other people! that which you see CONSTANTLY as a problem in other people you will increasingly worry about in yourself.
if you can live with being annoyed sometimes and treat it like it's not a big deal, it will be easier to accept and believe that the times you are naturally, as a human, annoying in some small way to other people are not actually a huge crisis where everyone hates you and is thinking badly about you. you can live with knowing sometimes people just clash a little and can be mature enough to brush it aside and see past it!
