Why do people say "what's up?" when they pass you in a hallway and then just keep walking? They are asking a question, and yet they are clearly not interested in your answer. Why don't they just say "hi" and leave it at that?
Next time you walk by someone, and they say "Hows It Going?" Follow them for the next 10 minutes, and explain how you feel, by talking about everything you have done since you woke up.
