It's a blog! Mainly of book reviews.
Bizarre attempt to blame parents' urge to suppress emotion (particularly crying) in boys on innate sex differences. This is entirely wrong, it's unmistakably cultural. Examine Mediaeval European literature for a bit and you will soon notice that the macho behaviour is to show your emotions in the most extreme fashion possible. When it comes to grief, for example, crying is hardly sufficient. One has to tear one's hair or beard, beat oneself, eulogise and swear revenge if appropriate. You can still see it to some extent in Hamlet where an OTT show of grief competition occurs when Ophelia dies. Exactly when "stiff upper lip" became the macho norm I'm not sure but it was certainly strong during the Victorian era.
