This thought has crossed my mind, and it seems there is a personality trait among some, that when they lose, they actually begin to dislike those who won. I have seen this before, but generally it is between people who actually “know” each other, and have long standing differences.
I do not quite understand it, but I have never been fond of that behavior. Maybe that’s why when I see it, red flags go up and screaming alarms sound, and a big bright sign lights up saying: “this person has issues." Internal warning to self: Watch out possible snippy, bitchy, aggression, may occur.
The sad (funny) thing is: that the winners are happy no matter what the loser says, but the loser losses even more by being sore, thus labeled “Sore loser.”
