Maybe we're really geezer nation--a land of short-term memory loss, where the problems are all about finding the dang grocery store where we left it yesterday, on some street that has changed over night, trees in different places, new parking lots, a freeway over pass that definitely was NOT there yesterday. Who can remember anymore anything so abstract as how to think about firefighters. And anyways, you have to be careful to stay out of the way of their speeding trucks, with those awful sirens. What's my phone number? Where are my keys?
