Sometimes you see someone doing something that does not fit at all with your idea of that person. You realise that, a lot of the time, you don't really know people, even one of your best friends.Instead, you get to know a little bit about that person - the little things they want to reveal, or inadvertently reveal - and then you make up a whole lot of rubbish that's your idea of the person.
