Maybe you wonder what it is us tour guides do when we are out in the night. A tour is a curious thing. I show you something you recognize and tell you something you know or don't know about it. I send you off to explore and wait for you to return. You always ask if we are going to see the White House. You somehow think that talking on your cell phone as you sit right behind me is totally fine. You laugh at my corny jokes. You want to know when FDR was built because it wasn't there the last time you were in DC. You wonder if I can take you to your hotel. You thank me and make my night worthwhile. Let's do it again tomorrow.
