Tertius finds a nickel in his bedroom minted in celebration of the Louisiana Purchase. I guess that it was issued in 2003, the two hundredth anniversary, which holds T's interest for a second or two because it was the year of his birth. (2003 that is. Not 1803.)
I use the rapidly closing window of opportunity in his attention span to mention that the Louisiana Purchase spawned the Lewis and Clark expedition.
"Were they real?" he asks.
"Lewis and Clark?" I echo. "Yes, they were real."
"Only I get them confused."
"Adam and Eve."
"A bit different," I assure him.
"Were Adam and Eve real too?"
Ah, now there's a whole other conversation.
