My favourite people have always been either teachers, tutors, instructors or work colleagues... 

If they are extremely friendly in the first encounter, well, they've caused a problem for themselves because I become attached and obsessed and the idolising begins... Why? I never get a chance to know the person on a friendship level so how can I become so emotionally dependent and attached so quickly? It's illogical... I get withdrawal when I'm not around them. 

They never hang around long enough to find out how I feel (I wish I could make friends with some of them, it would reasure me and stop my dependency on them), and everytime they disappear (after months, sometimes years of weekly or daily exposure for an hour or 2) and it takes me months to get over it, everytime. It's horrible.
