We had a woman in her 60s at work who was straight out of the same mold. She was morose, beaten down by life and thankful she had never brought kids into this miserable world. Needless to say, she was an ultra-leftist who thought government ownership of all industry was the best possible world. The strange thing is she worked in a venture-capital funded startup, the epitome of capitalist enterprise. More often than not, you find that leftists are all cut from the same cloth.
You sure you never worked at the Post Office?I have a woman in my unit exactly like the one you described.
