Why is it best friends are always the most annoying?

Haven't you ever had these things you liked doing like writing stories, writing poems or writing your blog in your spare time? Yeah, I do that a lot. I started writing poems when I was 9 but I stopped for some time cause too much school work. The same with writing stories, you've all heard of Pokemon right? Well I was sort of writing a Pokemon story in P5, well that's when I started anyway. I was writing it with my best friend Karen, who also likes Pokemon. I wrote like 22 Chapters but then the computer broke down and I lost my memory disk, how typical. So, if someone was writing stories, poems, blogs, and you were too, would you say that they were copying you? I wouldn't cause that would be like saying all the authors copied each other, they all copied the first person who started writing. That's not fair is it? Well today for some reason Molly just starts getting so annoyed at me because she believes I always copy her, on writing blogs, poems and stories, but seriously, I started doing that before I even met her! And I've been thinking of doing a blog for such a long time but I didn't know any sites, it's somewhere where I can just write things and it's not likely anyone is going to read it, it's a good way of letting my feeling, thoughts and emotions out, write it out. But Molly never seems to get this; everything always seems to be about her. If there's a problem then she probably wouldn't even listen, occasionally she might show some sympathy, but only for like 3 seconds! For example, my friends Kirsty's gran died, and Molly just gave her 3 seconds of sympathy and it was back to how her life sucks. She doesn't even seem to realize that the world does not revolve around her, friends might care about her problems, but not if she's always constantly on about her life and doesn't listen to anyone else's. Would you say that was a good friend? Well in a way she is a good friends, she's one of my best friends but sometimes she just has no idea how annoying she gets! It's not funny anymore, it was never funny! She's a funny person but also the most annoying. She gets annoyed about this or that, whenever we try to say something, doesn't care about our problems, it's always her's. How rude! Molly, I know you will be reading this some time or other, so let me tell you, you might be annoyed at us, but you have no idea how annoyed we are with you! Can't you ever try to solve something out through compromise? You always have to do something so that I feel like screaming at you. You might think it's funny to throw my maths things onto the grounds but I certainly don't and neither does anyone else in our maths class. Why do you think you're not everyone's friends and me and Kirsty can get along with any people we choose? It's 'cause you just can't solve anything responsibly, I've had enough! You have finally gotten onto my nerves. You always annoy me but now I've had just about enough and I've snapped. Why do you think I usually don't like getting annoyed at people, it's 'cause when I do it's because they've done something seriously annoying and I keep being annoyed at them for so long! I know you're thinking I don't get on with anyone I choose but I do! I even get along with Ranjini and Michael! He doesn't annoy me, he can actually be quite nice and so can Ranjini, unlike you! Molly, keep on like this and one day you will have no friends to tell your problems to, you'll have no friends to talk to! No one can stand a person who's always the way you are! It's so annoying! I'm sorry if I'm making you feel bad but I'm your friend Molly and I care about you, I'm saying this cause I don't want you to end up friendless one day, I do really care about you even if you really get on my nerves sometimes. That's what friends are for after all.
