Why do my friends always end up annoying me?

All of my closest friends annoy me so easily. For instance, one of them is really immature and spoiled with no comprehension of how lucky they are and how the world is for people outside of wealth, which they are unaware that they have. Another is very insecure, and will often be inauthentic to impress a person or even to convince themselves that they are something they are not. Or, another one of them is so horribly, purposelessly, and unapologetically messy. Is it normal for people to be this annoyed with their friends? If so, how do they deal with this? If not, what's going wrong here?
