growing up or growing out

I think I'm over the cutesie thing, not a personal change just social. I don't need them to be cutesie, I need them to be shopisticated. Now I don't mind their cutesie nature but I when I need to talk to them about something that doesn't require their child-like behavior, I just don't see it happening. Maybe its fine for now but later, I feel like it just won't work. Its not a matter of need, but what everyone will be happy with. They are happy, but I am not always happy and sometimes feel that I have nothing to be happy about with them, just a slight high that can only be quenched rarely. Maybe I have to adjust, but I feel that I have adjusted nicely already and I just haven't found "that" I need.
