Have you ever..

met someone you just don't like? It's not that they have said/done anything in particular to annoy you (at least not at the start, when you decide you don't like them) you just don't like them? Then of course they say something (or do something) that really annoys you (or makes you mad, or..) and you end up saying "see! I knew there was a reason I didn't like them.." OI.
