How far is the next atom over?

To quote the skeptic down the street; "how far is far?" if you try to calculate the distance to anything you have to make certain assumptions. You have to assume the space in between is the same kind of space at each point. And that's just the beginning. So how far is it to the nearest star? 4.2421 light years. How far is the nearest pharmacy? This is a little harder for me to answer. How far is it to enlightenment? This is impossible for me to answer. Here's the thing: our knowledge of the first question's answer has changed the most. Our answer to the second question has been the most relative. Our answer to the last question has, in my opinion, always lacked something. Sometimes it lacks a bases in reality sometimes it lacks a bases in thought. So how close am I to the person next to me? How far are we to our neighbor? How far are you to the ones near you? And how close are you to yourself? How close are you to the ones you love? How close are you to happiness? It's not the answer that's important but the question to be considered.
