"In Between" is NOT a place!

So this may seem like a really dumb argument, especially when you consider the two sides of the argument are not children. Yes folks, we're talking about grown adults in their 30s. Ain't life grand?

My supervisor and I were talking about when I would have my coaching session for the week. I asked him if I should plan on it when I returned from my lunch. His response was, "Yes. Unless I'm not here because then I'm there, but if I'm not there then I'm in between." My answer: "In between in not a place!" Thus the argument began. Sigh. Really, two grown adults. One man. One woman.

The woman states, "In between in NOT a place, because you're not here or there. You could be anywhere or somewhere."
The man says, "Yes it is, because I'm not here or there, I'm in between."

We even pulled another "neutral" 3rd party into it. It was another man. We wanted a decision on who was right. His remarks were that he could see both perspectives. Really folks. Someone has to be right and I vote for the woman! Me, of course.

You can be here, there, anywhere, somewhere, everywhere, and nowhere, but clearly "in between" is not a place. Notice the similarities in the above list of words. All of them have "ere" at the end. "In between" doesn't have the letter 'r' to make the "ere".

So we put it to you fine people.... Is "in between" a place? Let me know!
