It's called Human Nature. You buy a TV for $1000 and show it off to your neighbour who says he bought exactly the same TV for $400, you don't think that will effect you at all?
If you just say "oh well, I thought $1000 dollars was a fair price" and think no more of it - well you are a better person than I am!
