seriously, thats what i've been wondering for so long.. and i came up with one theory that maybe they want people who don't become too attached or emotionally involved with whoever they are working with.. and thats where i think i differ, like if anyone tells me something wrong thats happened to them or any strong emotions they feel (not dirty lol) i find it hard to just not feel their anxiety/saddness/whatever is the problem.. its like very strong empathy, and it does effect me, a lot.. like they might get over the problem in a blink of an eye, but i'm there still trying to figure a way to make it all right.. anywayy, i should stop that, because a) its not good for me, b) i shouldn't have to take on the problems of everyone and try to sort them, its their battles to fight and c) i've been caught up like this before and don't want it happening again.
so thats why i think they employ heartless, stony faced people.
