I'm the type of person who notices patterns really well. They even said so when I was being tested as a kid to see what was wrong with me, apparently my iq is very high so I seem retarded to actual retards because they're too dumb to know they're the dumb ones. This makes me very good at "reading" people, and at first I didn't understand it but as I aged I learned to trust my gut. So if someone was shitty to me if I notice someone with the same paterns as the person who was shitty to me I know now they're likely to be a similar kind of person to the one who was shitty to me, and are thus likely to be shitty to me, and lo and behold I'm usually right.
