If someone doesnt like you....

I haven't seen many people like that....If I dont like someone yet decide to give them a chance...it will always be in back of my mind that i dont like this person...and when something happens, i can just say, my instincts were right to not like this person"

Exactly.

Is it pessimistic or skeptical to say...people never change? So if you dont get along with someone as an adult....u probably never will, no matter how much one "Matures" or changes..... or else its very rare.
