There are those who will look at this survey and assume that the reason girls are not as happy is due to sexism or some kind of discrimination. What’s odd, though, is that many of the countries that we think of as the most egalitarian in terms of their attitudes toward gender contain some of the biggest gender gaps in happiness.

Which one do you choose and why? I personally choose unhappy women. I kinda like them emo, depressed and jaded.
