Heaven knows I would be rich if I got money for every time I have had people ask me about dinosaur bones after learning I'm an archaeologist. They are so disappointed when I tell them that is a question for a paleontologist. Ah well. Now when I am out in the gardens I get people asking about all sorts of plants, and they have that same look of disappointment when I tell them I really don't know enough about roses, or whatever, to help them.
