If someone hates everyone, how does that person even survive socially? In fact, how did the incredibly friendly Coupon Mike end up being married to the Eye of Sauron?
The woman I know had marginal friends through high school, and her boyfriends didn't last long due to her perpetual and ever-present jealousy -- not only directed toward other females, but also toward any "guy time" he would spend with his buddies. I think at some point she took some sage advice, such as "catch more flies with honey than vinegar," and was able to turn off the rage machine long enough to last through the nuptials.
Once ensnared, the captive male acted much like Coupon Mike -- a decent and personable guy when the warden isn't around.
Hah. You just described my mother.....God rest her soul. The only thing I would add is she also hated everything.
