I can state unequivocally that the facial musculature (the so-call sourpuss) is responding to a female hormone (PITAerone) that is secreted at menarche. This renders the young adolescent female incapable of expressing pleasure in the presence of anyone over the age of 23. There is a genetic component so the muscular distortion is most evident to the closest adult relative of either sex. The addition of another adolescent female will sometimes mitigate the facial reaction. The effect of PITAerone may last for several years but it does weaken about age 19, give or take ( only to return after several years of marriage and children but then it is spouse-directed). There is no treatment (other than time), but ignoring it sometimes produces results...directly confronting the situation has as much success as "turning back the sea." Reason plays no role in dealing with the young adolescent female.
Despite my deep medical background and experience, I have been reluctant to express medical views on the Forum...but I cannot remain silent when my fellow Forum members are confronted by the...SOURPUSS.
Now as far as the male adolescent.....
Please note, I will not respond to PM on the subject
and the FDA ( when it is not dissing salsa) requires me to state that my comments have not been approved by the FDA...which actually increases my credibility.
I am not signing my real name for obvious reasons as I am not licensed in NH.
