An “owlet” is apparently a small little tiny owl or perhaps a not quite old yet young in the tooth (do birds – outside of dinosaur birds – even have teeth?!) type of owl.
And I made this little thing up for somebody who seems to like these “owlets” that you have been hearing so much about – I mean just look up there at that first sentence . . . you got practically a dictionary.com type of definition there – and who could ask for more than the precious gift of knowledge – harumph . . .
And I’m go-go-gone . . .
