A woman is in a hardware store and picks up a hammer. When she is checking out, the shop owner says, “What are you going to use this hammer for?” And she says, “My husband told me to buy a hammer. We’re putting up some pictures in the kitchen.” The owner might say, “Okay. But this is a professional carpenter’s hammer. For your purpose, that one over there would do just fine, and it’s a third the price.” That’s the difference between a relationship and a transaction.
