Sometimes things just don’t click. For example, have you ever had a conversation with someone and when you walked away, the first thought that popped into your head was, “What the heck did we just talk about?” Typically this is because each of you had a different take on what the core issue of your conversation actually was. For instance, think about your last argument — I mean misunderstanding — with your wife. While you thought she was upset that your parents were coming for a visit, she was really mad about the fact that you forgot to take out the trash — the whole parents thing will come later. In a sense this is kind of like all the teeth gnashing that surrounds the level of confusion around the debates about data center architectures.
