Gender roles are seriously getting so old, and every time we think some serious progress had been made, a thread like this shows up and we are confronted with the fact that we still have a loooong way to go. Yes, we've come a long way from 'boys wear blue and girls wear pink,' or 'boys don't cry.' But these social norms didn't just disappear into thin air. Even if they're not pushed onto us as overtly as, say, the 50's, doesn't mean the ideas don't linger into our minds every time we make a decision about what to wear, or how to sit.
Basically, things are better, but we haven't entirely broken strict expectations for gender expression. But one day we will, as Miley Cyrus once said, "It's the climb."
