Not all. Maybe is a cultural thing around here. Some feel entitled to make conclusions about others behaviours because they know how to name it and they understand it, it's not just only a way to behave as for anybody else is, it has another meaning. The fine line between normal and deviation gets a name. I guess.
They learn to judge behaviours and the learning goes beyond the patients' setting.
Being abnormal is most of the time part of being normal, but...
I don't understand it either totally.
