Tbh I really hate kids because just like you no offense they always have something to talk about not worth talking about. They either scream, talk too much, or just say dumb stuff, act like a know it all. I've met about 2 cool kids under 13 who are just chill as -blam!-, don't scream, don't profanely curse like a sailor, crack humorous jokes and are fun to actually play with. I rarely don't want to play with someone because they have an annoying voice, but to be completely honest I've had some kids whose voices just make my ears want to bleed from being so high pitched and loud. Overall, it's a game not real life. If an 15 year old doesn't want to play with you, you shouldn't want to play with him. Find solace in those 6-9 year olds you play with. Those are your real friends. Trust me, befriending the older kids isn't really worth it anyways. There's usually a generation gap pretty noticeable and chances are they will be different than you anyways and won't connect on the same level as people your age.
