I've read somewhere that an abusive family background can have that affect, wich can basically be the reason for social anxiety also. I guess they go hand in hand many times.
I've always felt like when i did my homework i was just reading the **** over and over again, rarely memorising anything. Thought it was something normal but i don't think it should've been quite like that.
Another thing is that i have always had this problem about following a story (movies, books, you get the point). The timeline for example is one of the things i always find my self thinking about when it should be pretty ****ing obvious. I was that guy who used to ask things like "is he the actual one who did this or that" when most of the time it haven't even been made clearified yet.
It's also seems that i have some kind of overactive concentration thing going on, basically sitting there and studying those damn subtitles when i basically could've just sweeped through them or just listened to what was actually being said. The more i actually focus it seems the less i register the information...
