My best friend and i have never been in a serious fight and agree on everything except for two or three things. but recently I've been getting annoyed at her and not wanting to hang out with her when before i couldnt wait to c her. I get annoyed at how she thinks some things r right when i think there wrong, her hating people when i think there okay, and her not liking the people i talk to. There r more things im getting angry at besides that but those three r the ones that happen daily. Is this a normal thing or should i try and get a new best friend?

P.s.- were both 16 and she is not very mature. Maybe this is another reason im getting irritated...
