I used to hang around with mostly people my age, now im 17 i seem to be with people 25+ only. most of the people my age still have teenage problems and wish to sit talking about them and the universe on a very regular basis....now i dont have any problems that i need to share and theres only a certain amount of time i can spend chatting about crap; so is it normal for me to want to hang around with more 'mature' people and become frustrated with my friends at this age?
