all in an elavator

I sit in the lobby, and I'm alone. The elvator doors directly across from me open with the familiar, bing. No one's inside. There's no doubt in my mind that this event took place directly in front of my eyes for a reason. It gets me thinking. Thinking about how elavators are really just holding cells, one of those few places where life gets put on hold until the next floor's business meeting or sale in the mall. It's strange, strange to think about how they move people without people having to move themselves,or do they move people in more ways than one?
