Tinuviel said it much more eloquently than I ever could: Yes some girls f**k with guys heads, but some guys f**k with ours too. Both genders can be ambiguous, both can be irrational, ruled by the heart etc, but both can also be logical and calm. It comes down to the person, and anyone who says a blanket statement like "Boys are stupid" or "Women are so irrational!" is a sexist in my eyes. End of.
