I am not trying to claim that I am not affected by peer pressure at all, I am far from that. If my brother suggests anything I automatically like it because I am pretty sure that he is the coolest person to ever walk the Earth (besides Jesus). On the other hand, if my sister suggests music, I am bound to hate it. Now, this mostly has to do with the fact that my brother and I have very similar tastes while my little sister is the exact opposite of me in most things, but also because I wish to identify more with my brother's subculture than my sister's preppy, fashionable one.
So, I have resigned myself to the fact that I will always be influenced by others in my choices, but also challenged myself to think for myself. If being a 'hipster' means that I have to only listen to obscure, indie music and never like anything mainstream, then I am not a hipster. However, if being a hipster means that I can rock out with a sonic screwdriver in my prom dress while blasting Celtic punk after playing Assassin's Creed, then hell yeah I'm a hipster!
