Hmm.... Maybe I am now ready to confirm this theory of mine :

"I never mistake about people! "

Or something like this one :

"I come to the very final conclusion about people at the very first glance"


It means...If I am interested in someone at the very first glance, or liked him/her at the first moment, it is the exact reality about him/her. Even if I change my mind time to time, the sound final truth is that I like him/her.
