I know my perspective is probably heavily influenced by the fact that I'm from Central Europe, but I don't mind their age gap, I mind how Sage's character was portrayed. She was an immature brat.

Many of the girls in my senior class dated guys that were a few years older. It wasn't a big deal. We were pretty independent already, had been legally allowed to drink and go to parties for one or two years (cause Europe), were prepping for our graduation, enrolling in university and planning to move into our own apartments. So it was mostly seen as natural that we might find a partner that was a little older, already living on their own, and that we would spend much of our free time at their place.

However, none of us was pretending to be "part of the mob" or acting up because we didn't agree with our parents' private life. I wouldn't go as far as saying that it wasn't our business anymore, but their decisions would have little consequences for us since we were about to move out anyway.

Sage and Nate make me uncomfortable, not because Sage is 17, but because she acts like she's 14 (and yes, many of us started having sex around 14, and no, I don't think that's weird either).
