Jennifer:--If you had to describe this whistle, would you classify it as a friendly whistle. For instance: the whistle that the Dwarves (Dwarfs?) used in Walt Disneys' "Snow White" (hi-ho hi-ho it's off to work we go) would be friendly. Is it a whistle of unexpected surpise? Is it more of a whistle that would heard from a construction worker who has spied a good looking gal? How about the whistle from a tea kettle? In order to make the proper judgement in this matter, I could use a little more input. To your knowledge are you the only one that experiences this whistle?
