Does everyone know a person that every time you speak to them it feels like getting bit by a snake. I think it was covered in Bridget jones, the jelly fish lady? The person seems intent on just one uping everything you say or attempting to make you feel inadequate in some way.
My question is, why do you think these people are like this? And if everyone knows someone like this, is it possible it isn't the person doing it intentionally at all but rather they are tapping into unconscious inadequacies without realizing?
