PHP: somebody gives you an orange one day and before eating it you think to yourself: there might be some good money in oranges. So you get some wood, some cardboard boxes and you build yourself a little orange juice stand. But you never get past the first costumers. So you invest a little bit. You hire the Indian boy who lives down the street and he paints your stand for a modest amount. You wait a while, but you're not still not getting any costumers. So you give up on the idea altogether and abandon your little stand. A week later you pass by and notice somebody else is using it. Even the oranges are the same; you marked them. You casually mention that you built the stand. The clerk says his boss is not around, but he offers you some free juice. You're thirsty, so you accept it.
