When it comes to similarities, it is shocking to know that boys and girls have some things in common. But even then, nothing can be more of an overstatement. Whoever said men are from Mars and women are from Venus had it right. To put it simply, we are from different worlds.
Men would rather have beers with the buds, while women would rather catch up with her girlfriends over coffee. Men have to smell his clothes to determine whether it's clean, women know the exact date, time, and shop where said article of clothing was bought.
In a woman's room, she knows exactly where everything is. Men have to dig for treasure. Women speak because they wish to speak, whereas a man speaks only when driven by something outside himself - like, for instance, he can't find any clean socks.
Of course, there are always a few notable exceptions. One must never forget the titles so graciously given - "every girl's boyfriend" for the effeminate hetero and "one of the boys" for the boyish female.
