You konw some people just have psychological issues. For example, a short man will treat a tall beautiful woman with some kind of bad attitude because he feels threatened; a man with low level of education will consider a woman with PhD degree a wierdo....
not quite right. after a girl gets her PhD, she gradually feels elevated and might become condescending to her peers and husband, too. her attitude might slowly change overtime due to her degree, especially when her husband has a lower degree (a master or bachelor only).
you may argue you are not the case, which might be true. first, every girl is not the same as you. second, if a girl finds her true love, she might put her degree away (same for a boy). however, if her marriage is not 100% to her satisfaction, she might not feel she found her true love. in this case, her superiority originating from her academic success may potentially return and grow up robustly and unnoticably.
