I think you're absolutely right!!!!
According to a lot of mother/child observers, mothers are more likely to explore possible reasons another child is crying or laughing, etc... with a female child than with a male child. Her response with a male child is often "He must be sad", whereas with a female child she's far more likely to propose possible reasons the crying child might be sad as well as asking her female child what makes her sad, etc....
Mothers are also more likely to be generally more talkative with their female children, even as infants.
Fathers, having already been brought up under a regime which denies their right to emotions, talk little about emotions with either male or female children.
It seems to me that it's just so ingrained in our society to assume that males simply are both less interested in and experience fewer emotions. Whether we realize it or not -- due to the media misinterpreting things -- most men who are vocally in support of feminist thought are largely supportive because of this sort of thing. Feminists not only want "equal rights" for women, but for men as well, especially the right to have an emotionally satisfying life, which includes the right to not be emotionally abused into emotional lack by other males.
